    OVERVIEW
    Gadiel Romero pleaded guilty to conspiracy to commit
    kidnapping and got a 276-month prison sentence, a below-guidelines
    sentence — his guidelines range was 360 months to life.                    Ably
    represented on appeal by new counsel, Romero principally claims
    that    his   incarcerative   term   is   both     procedurally   flawed   and
    substantively unreasonable. Concluding, as we do, that his attacks
    miss the mark, we affirm.
    HOW THE CASE GOT HERE
    Because this appeal follows a guilty plea, we take the
    facts    from   the   undisputed     parts    of   the   probation   office's
    presentence report ("PSR") and the transcripts of the key court
    hearings.     See, e.g., United States v. Edwards, 
    857 F.3d 420
    , 421
    n.1 (1st Cir.), cert. denied, 
    138 S. Ct. 283
    (2017).
    Abduction
    Around 6 p.m. on July 23, 2012, masked gunmen abducted
    Manuel Amparo and Jose Daniel Felipe Castro near a house on Allston
    Street in Lawrence, Massachusetts.             What happened is this.       As
    Amparo and Castro pulled into the driveway in Amparo's car, a white
    van pulled in behind them and four men wearing masks and black t-
    shirts emblazoned "POLICE" charged out shouting "police."              Three
    of the men had pistols and the fourth had a shotgun.              One of the
    - 2 -
    men smacked Amparo on the side of his face and forced him and
    Castro into the van.     The men then put a hood over Amparo's head
    and bound his feet and hands.     The van sped off to Manchester, New
    Hampshire, it turns out.     Responding to a 911 call from Amparo's
    wife, police found a plastic handcuff on the ground near Amparo's
    car and a GPS locator attached to the car's back bumper.
    During   the   drive   to   the   Granite   State,   Amparo    was
    periodically beaten (this part of the PSR is phrased in the passive
    voice). The abductors eventually brought him and Castro to a house
    in Manchester.    One of the abductors put Amparo on the phone with
    someone who threatened to kill him if he did not pay a ransom.            An
    abductor also burned him with a hot iron and repeatedly punched
    and kicked him.
    At some point that night, Amparo freed his hands and
    feet, removed his hood, and escaped through a window.          He started
    knocking on the neighbors' doors, looking for help.        Responding to
    the commotion, one neighbor called the police and said he had a
    man on his porch who claimed he had been kidnapped.              This was
    around 4:30 a.m. on July 24.
    Investigation and Arrests
    Arriving on the scene, officers heard from Amparo about
    his ordeal, including where he had escaped from.        And they learned
    too that the suspects and another victim where still there.             With
    - 3 -
    backup help, the officers headed to the location, freed Castro,
    and arrested Jose Guzman, Henry Maldonado, and Thomas Wallace.
    Searches (either with a party's consent or with a warrant) later
    revealed   guns,   police   paraphernalia   (badges,     t-shirts   with
    "POLICE" on them, handcuffs, etc.), Amparo's wallet, cell phones,
    and blood on the van's carpet.
    During the investigation, law enforcement learned that
    Guzman, Maldonado, and Wallace participated in a Lawrence-area
    kidnapping gang led by Danny Veloz (nicknamed "Maestro") that also
    included Romero, Luis Reynoso, and Jose Matos.         The crew focused
    on abducting drug dealers and holding them for ransom (in the form
    of cash or drugs).      Guzman, Maldonado, Wallace, and Reynoso
    cooperated with the government.      From their statements, a clear
    picture emerged of the Amparo/Castro abductions.        Matos installed
    the GPS tracker on Amparo's car and stored uniforms and weapons
    used during the kidnapping.    Veloz tracked the GPS data and clued
    the crew in on Amparo's whereabouts by calling Guzman.       When Veloz
    said Amparo was near his Lawrence home, Guzman, Maldonado, Wallace,
    Reynoso, and Romero grabbed Amparo and Castro at gunpoint.          Once
    at Maldonado's Manchester home, Veloz and Guzman continued to talk
    by phone throughout the evening as Maldonado tortured Amparo to
    get him to pay a ransom.      Eventually, Wallace drove Reynoso and
    - 4 -
    Romero back to Lawrence (Maldonado and Guzman stayed with the two
    abductees) and then returned to Maldonado's home.
    Beyond that, the cooperating witnesses also talked about
    a May 9, 2012 attempted kidnapping on Saratoga Street in Lawrence,
    and   a   July    8,    2012    kidnapping    on   Whiting   Street     in   Lynn,
    Massachusetts.         Guzman fingered Romero as part of the crew present
    on Saratoga Street for the attempted kidnapping (the attempt fell
    through    when    the    police    responded      to   reports   of   suspicious
    activity).       Guzman and Maldonado also fingered Romero as part of
    the Whiting Street crew that kidnapped a drug dealer at gunpoint
    and kept him in Maldonado's basement (Guzman and Romero beat and
    kicked him, apparently) until the dealer's associate paid a ransom.
    Indictment
    After his arrest, a federal grand jury indicted Romero
    — along with Guzman, Maldonado, Wallace, Veloz, Reynoso, and Matos
    — for conspiring to "unlawfully seize, confine, kidnap, abduct,
    and carry away" two persons "and to willfully transport them in
    interstate commerce and hold them in ransom, in violation of" 18
    U.S.C. § 1201(a) and (c).           Reduced to its essentials, § 1201(a)
    punishes    anyone      who    "unlawfully    seizes,    confines,     inveigles,
    decoys, kidnaps, abducts, or carries away and holds for ransom or
    reward or otherwise any person . . . when . . . the person is
    willfully transported in interstate or foreign commerce . . . ."
    - 5 -
    And § 1201(c) provides that "[i]f two or more persons conspire to
    violate this section and one or more of such persons do any overt
    act to effect the object of the conspiracy, each shall be punished
    by imprisonment for any term of years or for life."               Romero
    initially pleaded not guilty to the charge.
    Recorded Conversation
    During Romero's pretrial detention, his then-attorney
    gave prosecutors a letter that he said Romero had given him.
    Signed     by   Maldonado,   the   letter   purported   to   recant   his
    identification of Romero as a player in the July 23 kidnapping.
    Maldonado told prosecutors in an interview that he wrote the letter
    because Romero had threatened him by showing him a shank and having
    some guys tell him they knew where his family lived (Maldonado has
    a wife and two children).          A later search of Romero's cell
    uncovered a tooth brush sharpened to a point.
    Maldonado agreed to wear a secret recording device and
    talk to Romero in prison about Romero's plan to have him recant
    his identification.      And the tape captured Romero inculpating
    himself in the July 23 conspiracy.          Here is a taste of what he
    said:
    I was the first one that hit [Amparo], 'Be quiet,' and
    then [Wallace] hit him hard. Bang! Bang! Bang! Holy
    shit! . . .     [Wallace] cracked him. When I hit him
    . . . he bled a little bit, but when that dude hit him
    with the grip of the shotgun, . . . blood was spurting
    everywhere!   That poor [Reynoso] in the back . . . .
    - 6 -
    This is the third time I went to do something with
    [Reynoso]. . . . He's not built for that.
    And while complaining about what Veloz had paid him for his
    participation, Romero also said:
    I was out there doing my thing on my own too. Do you
    remember one time when he says to me [unintelligible],
    Oh, how did you buy that car? Not with you . . . . The
    most I ever see you with, motherfuckers is five stacks
    . . . . I went with another team and I make 50 stacks
    one night. One night, one hit. With [Veloz] it's 5, 5,
    5. No more . . . . It's like, you don't want us to get
    fat, you want us to, like maintain and go.
    The two then shifted to a discussion about the letter
    Maldonado had given his attorney. "Listen off the book," Maldonado
    began,
    [Guzman's] the one . . . when we first, listen got when
    we first got, first got in the tank together, [Guzman's]
    — he's a dirty dude — all through this he told me,
    yo. . . . At first he tried to tell me in Spanish to
    tell [Veloz] to swear about everything about the guns
    and everything and then he said "Yo, . . . tell them
    that it was [Veloz] and [Romero] that put you up to all
    of this you heard?
    "If you said this shit to your attorney," Romero responded, "I can
    leave."   To that, Maldonado replied:
    My man . . . I've . . . told them exactly everything
    that I wrote in the letter everything. Everything that
    you told me to tell him. Everything, and . . . I haven't
    still come face to face with the dude with the prosecutor
    but when I do come with the prosecutor even though I
    know he's gonna know that I'm lying it doesn't matter
    cause it's my word, you know what I'm saying.
    "I don't know how . . . that shit works," Romero stated, "because
    if you already went to a grand jury . . . [a]nd you gave a
    - 7 -
    confession, then, they gonna hit you with perjury."              And later in
    the conversation, Romero said to Maldonado that "if you say . . .
    what you were just telling me . . ., that in the pen . . . [Guzman]
    said . . . 'We are going to say that it was [Romero] and [Veloz]'
    that thing gets me out of this mess . . . ."           "Everything you told
    me to say I'm gonna say," Maldonado stressed.           "I'm gonna tell my
    other lawyer that:      'Yo, [Romero] had nothing to do with . . .
    this and that.'"
    Romero   also    brought     up   the   alleged     ransom   with
    Maldonado.      Calling Amparo "a kilo carrier," Romero opined that
    the government will "need [Amparo] to go to court to testify."
    But "if the guy is intelligent and he knows what happened," Romero
    added, "he won't go to court," because if he testifies about
    everything — how the crew put "a GPS under [the] car" and "ask[ed]
    for ransom money for [his] head" — the government will know "that
    [he was] doing something big," which would get the "feds" on him.
    Change of Plea
    Represented by counsel, Romero attended a change-of-plea
    hearing where he switched his plea from not guilty of conspiracy
    to kidnap to guilty (he did so without a written plea agreement
    with the government).        Here are the highlights from that hearing.
    Near the hearing's beginning, the judge noted that the
    statute   the    government     alleged    Romero    conspired    to   violate
    - 8 -
    criminalizes the "knowing[] and willful[]" abduction of "a person
    with the intent to receive a benefit, usually in the form of a
    ransom or reward . . . ."    The judge also touched on the law of
    conspiracy, the details of which are not relevant here.      Romero
    said he understood. And the judge discussed how federal sentencing
    works, noting in broad strokes that a court first calculates the
    applicable advisory-sentencing "range" — after accounting for the
    base "offense level," any "adjustment[s]" to the offense level,
    and the defendant's criminal history — and then considers various
    "factors" to come up with an appropriate sentence, whether within,
    above, or below the range.   "Ultimately," the judge said,
    I have to see . . ., as best as I can . . ., that justice
    is being done in the case, so there will be a [PSR]
    prepared. It will be shared with you, obviously, with
    me and with the government, and where there are
    disagreements, we have a hearing, and that's where we
    have an opportunity to work out finally what satisfies
    me as a fair and just sentence, and, of course, you have
    an opportunity to participate in that process and to
    speak at [the] hearing as well.
    Asked by the judge if he had any questions about sentencing, Romero
    answered that he did not.
    Because he had to see if Romero accepted responsibility
    for committing the charged offense, the judge had the government
    summarize the evidence against him.     Among other details, the
    government emphasized that the crew had "held" the kidnapped
    victims, "and a ransom demand was made on one of [them] for his
    - 9 -
    release."     Romero did not dispute anything the government said.
    Taking a belt-and-suspenders approach, the judge then repeated for
    Romero's benefit the gist of the government's evidence — evidence
    that   included    (in   the   judge's   words)   his   being   "part    of    an
    agreement to kidnap" and transport a person across state lines
    "with the intent to procur[e] a ransom for his release."                "[W]ere
    you part of that agreement with Mr. Veloz and others?" the judge
    asked Romero.      "Yes, sir," replied Romero, who then acknowledged
    that he was "voluntarily" choosing to plead guilty. And with that,
    the judge accepted Romero's change of plea.
    Sentencing
    After the change-of-plea hearing, probation prepared the
    PSR, which recounted the pertinent facts in great detail.                     And
    among the facts described there was the ransom aspect of the
    conspiracy.       For instance, the PSR noted that Amparo told the
    police that Veloz threatened to kill him if he did not pay a
    ransom.     The PSR also noted that the cooperating co-conspirators
    (to quote the PSR) admitted that "the crew tried to get Amparo to
    pay a ransom."
    Because the conspiracy charged the kidnapping of two
    distinct victims — Amparo and Castro — the PSR treated Romero's
    - 10 -
    conviction as two separate counts of conspiracy to kidnap.1           See
    USSG § 1B1.2(d).   The PSR set Romero's base-offense level for each
    count at 32, see 
    id. § 2A4.1(a),
    and added 2 levels because he
    used a dangerous weapon, see 
    id. § 2A4.1(b)(3).
    On the conspiracy-
    to-kidnap-Amparo count, the PSR added 2 levels because Amparo
    sustained serious bodily injury, see 
    id. 2A4.1(b)(2)(B), and
    6
    levels because of the ransom demand, see 
    id. 2A4.1(b)(1). The
    PSR
    then adjusted the base-offense level for each count upwards 2
    levels for obstruction of justice (because Romero schemed to have
    Maldonado retract his identification).      See 
    id. § 3C1.1.
         All of
    this resulted in adjusted-offense levels for the Amparo and Castro
    kidnappings of 44 and 36, respectively.
    Applying a multi-count adjustment, the PSR calculated a
    combined adjusted-offense level of 45.      See 
    id. § 3D1.4.
        The PSR
    then reduced that number 3 levels for acceptance of responsibility,
    for a total-offense level of 42, see 
    id. § 3E1.1(a),
    (b) — which
    combined with Romero's criminal-history category of VI resulted in
    an advisory-sentencing range of 360 months to life in prison.2
    1 Probation   applied   the   2016   version   of   the   sentencing
    guidelines.
    2Despite putting in a "request[]," probation had not received
    information about "whether a ransom demand was made specific to
    Castro and whether Castro sustained any injuries." But probation
    said that, regardless, Romero's advisory-sentencing range "would
    not be impacted, and would remain 360 months to life."
    - 11 -
    Romero raised a multitude of objections to the PSR.              As
    pertinent here, he disagreed with the PSR's recommended 2-level
    increase for obstruction of justice — his theory being that the
    recorded conversation contained "no indication . . . that [he]
    threatened, cajoled, forced, [or] enticed . . . Maldonado to do
    anything or corroborated any previous threats, cajoling[,] or
    force against Maldonado to do anything on . . . [his] behalf."
    Romero also insisted that he played only a minor part in the
    criminal activity and so should get a 2-level minor-role reduction.
    See 
    id. § 3B1.2(b).
         He did not object to the 6-level ransom-
    demand enhancement, however.
    Probation    responded    that    even   without    the    recorded
    conversation,   a   preponderance   of     the   evidence    supported    the
    obstruction-of-justice    enhancement      given   Maldonado's      statement
    that he penned the letter recanting his identification after Romero
    (who had a shank) threatened him.          And probation insisted that
    Romero should not get a minor-role reduction because he "played an
    active role in the abduction of the two victims at gunpoint."
    Probation also noted that the evidence suggested that Romero had
    a hand in the May 9 attempted kidnapping (on Saratoga Street) and
    the July 8 kidnapping (on Whiting Street).         So probation concluded
    that the PSR properly assigned Romero's total-offense level of 42.
    And probation noted that even if the district judge agreed with
    - 12 -
    Romero on both objections, the total-offense level would be 38,
    which would still yield a recommended-sentencing range of 360
    months to life.
    Romero filed a sentencing memo.               Noting that the PSR
    recommended a sentencing range of 360 months to life imprisonment,
    he asked for a 120-month term based on his minor role in the
    conspiracy, his not threatening Maldonado, and his "substantial"
    steps he had taken "toward rehabilitation."               He did not mention
    the ransom-demand evidence, however.
    In     its   sentencing    memo,    the   government     noted   how
    cooperating co-conspirators "identified [Romero] as a member of a
    violent crew that kidnapped drug dealers for ransom" — like other
    crew members, he "disguised himself as a police officer, armed
    himself with a firearm, and abducted drug dealers for ransom."              As
    for the kidnapping of Amparo and Castro, the government chronicled
    how "Amparo was tortured with a hot iron in Maldonado's home while
    Veloz demanded a ransom from him (Romero did not do the actual
    burning but was present when it occurred)."              Romero was hardly "a
    minor player," the government emphasized — based on what the
    cooperating      co-conspirators     said,    he   was    "an   active,   eager
    participant in a conspiracy to kidnap multiple drug dealers at
    gunpoint   for    ransom."    And     once    caught,    Romero   "threatened"
    Maldonado, a cooperating co-conspirator, "causing Maldonado to
    - 13 -
    recant his identification of Romero."                     Still, the government
    recommended a 312-month prison stint, below the PSR's recommended
    range of 360 months to life.
    At sentencing, the judge indicated that he had reviewed
    the PSR and the parties' memos.                 And he noted that Romero had
    "some" objections to the PSR.            But because the government endorsed
    a 312-month sentence — a term below the recommended 360-months-
    to-life range "calculated by the Probation Office" — the judge was
    "not sure that those objections" were "all that relevant," since
    the government's proposal was "below" what Romero would get if he
    sustained     the     objections         and    reduced    the      offense         level
    accordingly.       The judge did not discuss Romero's objections any
    further, however.       And Romero did not object.
    The    judge   then    asked      for   argument    on   the     parties'
    "approach to the case and the recommendation."                        Obliging, the
    government     discussed      the    conspirators'         relative         levels     of
    culpability,       emphasizing     how    Veloz,     Guzman,    and   Romero        "most
    deserv[ed] . . . the kind of substantial penalties" permitted "for
    this type of offense" because they were basically "in the business
    of kidnapping drug dealers for ransom."                     The government then
    contrasted     these    co-conspirators           with    Matos,      who     did     not
    participate    directly     in     the    kidnappings,     and     with     Maldonado,
    Wallace, and Reynoso, who did participate directly but on fewer
    - 14 -
    occasions and in roles "subordinate . . . to persons [who] were
    more experienced, or who had a leadership aspect to the case."
    Conceding Romero was not a leader of the crew — Veloz was "the
    overall leader," and Guzman was "the street leader or street boss"
    — the government noted that Romero had boasted in the recorded
    conversation with Maldonado that he was among the crew's more
    experienced members.   This plus the cooperating co-conspirators'
    statements showed Romero "was engaged in this kind of activity on
    a regular basis."
    "You can't imagine a more dangerous, violent kind of
    conduct," the government stressed in something of a final pitch —
    "charging out of vans armed with guns, kidnapping, torturing"
    (Romero did not put the iron on Amparo, the government conceded,
    but he was there when it happened), "[a]ll to extort a ransom paid
    in drugs or money."    Yet despite the seriousness of the offense,
    the government supported a slight departure from the low end of
    the sentencing range because it thought Romero's criminal-history
    designation   significantly   overstated    the    seriousness      of   his
    criminal history.   Which is why the government requested a below-
    guidelines sentence of 312 months.
    Agreeing with the government's comment about Romero's
    criminal history, defense counsel asked for a sentence of 120
    months.   Counsel   emphasized    how   Romero    was   not   a   leader,   a
    - 15 -
    torturer, or a person responsible for securing the GPS device and
    equipping the crew.         He also suggested that Romero's recorded
    statements to Maldonado amounted to mere bolstering and failed to
    show obstruction of justice.               And he pointed out how Matos had
    gotten a 144-month sentence (Matos was the only co-defendant
    sentenced at that point), how the "national mean" sentence for
    kidnapping is 192 months, and how other defendants had received
    lighter sentences for similar offenses.
    After   considering         the   parties'    extensive      arguments,
    listening to Romero's statement (his "allocution," as it is called)
    where   he    professed    to   be    a    remorseful      and   changed    man,   and
    reviewing      the    pertinent      sentencing       factors,       see   18   U.S.C.
    § 3553(a), the judge chose to impose a 276-month term.                     Explaining
    his decisional calculus, the judge noted that several factors cut
    in favor of a below-guidelines sentence, including that Romero —
    though "very important in the organization," as the government
    said — was not "the mastermind"; that his criminal-history category
    was "overstated"; and that he had accepted responsibility for his
    crime and "taken some positive steps" to rehabilitate himself.
    But measuring "the other side of the equation," the judge "agree[d]
    with    the   government    that     this       was   a   violent,    brutal[,]    and
    reprehensible crime" for which "punishment is merited and earned."
    Also and importantly, in the statement-of-reasons form issued
    - 16 -
    after judgment entered, the judge checked a box indicating that he
    had "adopt[ed]" the PSR "without change."
    Anyone   wondering     about     Romero's    co-conspirators'
    sentences:      After a jury's guilty verdict on the conspiracy-to-
    kidnap charge, Veloz got a life term.           After they pleaded guilty
    to conspiracy to kidnap, Guzman got a 192-month term, Maldonado a
    156-month term, Wallace a 156-month term, and Reynoso a 131-month
    term.       And after he pleaded no contest to conspiracy to kidnap,
    Matos (as we said) got a 144-month term.
    OUR TAKE ON THE CASE
    That brings us to the present, with Romero's appeal
    challenging      (as   we   noted)     the    sentence's   procedural   and
    substantive reasonableness.3
    3
    Romero also argues — for the first time on appeal,
    engendering plain-error review — that the sentence violates his
    Eighth-Amendment right to be free from cruel and unusual
    punishment. He concedes that the case law is against him. Still,
    he raises the issue to preserve it for possible Supreme Court
    review. It is preserved, though (obviously) given the presence of
    authority contrary to his position, plain error is plainly missing
    here. See, e.g., United States v. Morosco, 
    822 F.3d 1
    , 21 (1st
    Cir. 2016).
    - 17 -
    Procedural Reasonableness
    Broadly speaking, Romero believes the judge botched the
    sentencing-range calculation by giving him enhancements for ransom
    demand and obstruction of justice, and by denying him a reduction
    for   minor    participation.        He   also    blasts     the    judge   for   not
    "expressly rul[ing]" on his objections to the PSR's handling of
    the obstruction-of-justice and minor-participant adjustments. The
    government, however, sees no reason for us to vacate his sentence.
    And we agree with the government.
    Standard of Review
    We generally inspect a procedural-reasonableness claim
    for abuse of discretion, see United States v. Tanco-Pizarro, 
    892 F.3d 472
    , 478 (1st Cir.), cert. denied, 
    2018 WL 4361944
    (2018) —
    a   multidimensional      test   that     requires     us    to    assess   "factual
    findings for clear error, arguments that the [sentencer] erred in
    interpreting or applying the guidelines de novo, and judgment calls
    for   abuse    of   discretion      simpliciter,"      see    United     States   v.
    Trinidad-Acosta, 
    773 F.3d 298
    , 309 (1st Cir. 2014) (quoting United
    States v. Serunjogi, 
    767 F.3d 132
    , 142 (1st Cir. 2014)).                           Of
    course,   when      a   defendant     fails      to   preserve      a   procedural-
    reasonableness objection below, we review only for plain error.
    See 
    Tanco-Pizarro, 892 F.3d at 478-79
    .                And as everyone knows by
    now, the plain-error standard is a demanding one, requiring the
    - 18 -
    defendant to "show (1) error, (2) plainness, (3) prejudice, and
    (4) an outcome that is a miscarriage of justice or akin to it."
    
    Id. (quoting United
    States v. Edelkind, 
    467 F.3d 791
    , 797 (1st
    Cir. 2006)); see also United States v. Pires, 
    642 F.3d 1
    , 14 (1st
    Cir. 2011) (calling the plain-error standard "daunting").4     But
    when a party intentionally relinquishes or abandons an argument,
    we deem it waived, meaning it is unreviewable.   See, e.g., United
    States v. Coleman, 
    884 F.3d 67
    , 71 (1st Cir. 2018).
    Ransom Demand
    We start with Romero's complaint with the ransom-demand
    enhancement — a complaint he débuts here, so our review is at best
    limited to plain error.    Section 2A4.1(b)(1) of the guidelines
    calls for a 6-level increase "[i]f a ransom demand or a demand
    upon government was made . . . ."       In Romero's telling, that
    increase only applies if a kidnapper makes a ransom demand to
    someone "other than the victim."   To support his thesis, he relies
    4 "[F]or sound reason," we have said, "the plain error rule
    creates a high threshold where the supposed missteps are ones that
    no one noticed at the time or, if noticed, thought worthy of a
    timely objection." See United States v. Dehertogh, 
    696 F.3d 162
    ,
    170 (1st Cir. 2012).      For example, this "exceedingly tough"
    standard keeps the parties from hiding problems below — which
    could've been fixed then and there — so that they might argue error
    here. See Bielunas v. F/V Misty Dawn, Inc., 
    621 F.3d 72
    , 80 (1st
    Cir. 2010).
    - 19 -
    on a Seventh Circuit case, United States v. Reynolds, which held
    that "§ 2A4.1(b)(1) may be applied only if kidnappers' demands for
    money or other consideration reach someone other than the captured
    person."     See 
    714 F.3d 1039
    , 1044 (7th Cir. 2013) (internal
    quotation marks omitted).   And because the PSR indicates only that
    a ransom demand was made to Amparo himself, his argument continues,
    the judge had no business applying the ransom-demand enhancement.
    This matters, he submits, because without that enhancement his
    sentencing range would be 324 to 405 months, not 360 months to
    life.      See USSG Ch. 5, Pt. A (sentencing table) (setting a
    sentencing range of 324 to 405 months for persons with a criminal-
    history category of VI and an offense level of 36).          Though
    artfully framed, his argument fails for several reasons.
    For openers, and to repeat, Romero pleaded guilty to an
    indictment charging him with infracting 18 U.S.C. § 1201 by
    (emphasis ours) conspiring to kidnap two persons, transporting
    them interstate, and holding them "for ransom."      At his change-
    of-plea hearing, remember, he admitted (no ifs, ands, or buts)
    that the government's version of events added up to a § 1201
    violation — a version that prominently featured his having played
    a role in a kidnapping conspiracy where (double emphasis ours)
    "the victims were held and ransom demand was made on one of the
    victims for his release."     And by agreeing with the government
    - 20 -
    that he violated § 1201 when a ransom demand "was made" only on
    the kidnapped "victim[]," Romero arguably waived his current claim
    that no ransom demand was ever made because the demand did not
    reach a third party.     See generally United States v. Walker, 
    538 F.3d 21
    , 23 (1st Cir. 2008) (holding that a defendant waived any
    right to claim as error a sentencing rationale that she had agreed
    to in the district court); United States v. Turbides-Leonardo, 
    468 F.3d 34
    , 37-38 (1st Cir. 2006) (emphasizing in a similar context
    that "a defendant who eschews a warrantable objection" to a
    sentencing    enhancement      "lulls   both    the    prosecution      and   the
    sentencing court into what will prove to be a false sense of
    security if he is later allowed to do an about-face").
    But even assuming, favorably to Romero, that the claim
    is not waived, we discern no plain error.                    To win under this
    standard, Romero must show (among other things) that the judge
    committed    an   "indisputable"      error    by    (for    example)   flouting
    governing precedent or the guideline's clear text — such a showing
    would satisfy plain error's plainness prong, the case law holds.
    See United States v. Jones, 
    748 F.3d 64
    , 70 (1st Cir. 2014); see
    generally    United   States    v.   Olano,    
    507 U.S. 725
    ,   734   (1993)
    (explaining that "plain" error is "synonymous with clear or . . .
    obvious" error (internal quotation marks omitted)).                  This he has
    not done, however.
    - 21 -
    Romero   pins    his    plain-error        hopes   to   the   Seventh
    Circuit's Reynolds decision, which (as we noted) held that "'ransom
    demand' under § 2A4.1(b)(1) requires that a demand be made to a
    third    party."     
    See 714 F.3d at 1044
       (bold-face    type    and
    capitalization omitted).      But Reynolds does not — repeat, does not
    — control us, a fact that pokes a huge hole in his Reynolds-based
    argument.    See United States v. Richard, 
    234 F.3d 763
    , 771 (1st
    Cir. 2000) (finding no plain error even though a majority of
    circuits had adopted the interpretation of a statute urged by the
    defendant); see also United States v. Caraballo-Rodriguez, 
    480 F.3d 62
    , 70 (1st Cir. 2007) (same).
    Still trying to bring his claim within the sphere of
    controlling precedent, Romero notes that Reynolds cited a case of
    ours, United States v. Alvarez-Cuevas, 
    415 F.3d 121
    (1st Cir.
    2005).   But his effort is for naught.
    Alvarez-Cuevas        interpreted    a     different    subpart    of
    § 2A4.1 — (b)(6), not (b)(1).             As Alvarez-Cuevas said, subpart
    (b)(6) tells sentencers to jack up a defendant's offense level by
    3 if "the victim is a minor and, in exchange for money or other
    consideration, was placed in the care or custody of another person
    who had no legal right to such care or custody of the victim."
    See 
    id. at 122
    (quoting § 2A4.1(b)(6)).           The defendant in Alvarez-
    - 22 -
    Cuevas offered two reasons why that enhancement did not apply
    there:
    (1) the [kidnapped] child was never "placed in the care
    or custody of another person who had no legal right to
    such care or custody," because the enhancement refers to
    placing the victim in the custody of a third party, not
    one of the kidnappers; [and] (2) because [the two co-
    conspirators] who kept the child . . . were not paid
    money or other consideration to keep the child but rather
    merely expected to receive some of the proceeds of the
    ransom, the child was not placed in their custody "in
    exchange for money or other consideration."
    
    Id. at 124.
         Agreeing with the defendants, Alvarez-Cuevas held
    that subpart (b)(6) applies only "where the child is kidnapped, by
    special order, to be turned over to the custody of a third party
    who has no custody rights and who has paid the kidnappers to do
    the job," as well as where "the ransom-demanding kidnapper, who in
    an effort to make it harder to find the [child], pays a third party
    to keep and care for the child."    
    Id. at 122,
    126-27.    A contrary
    interpretation,    Alvarez-Cuevas   concluded,   "would   render   the
    'placed in the custody of another person' a nullity" and would
    "create[] . . . incentive[s] for kidnappers to hide or even to
    abandon children (thus avoiding responsibility for their custody
    or care)."    
    Id. at 127.
    Reynolds dropped a "cf." citation to Alvarez-Cuevas,
    with the following parenthetical:       "(construing § 2A4.1(b)(6) to
    apply only to situations involving third parties even though the
    section makes no explicit reference to them, because of additional
    - 23 -
    harm implicated in such 
    situations)." 714 F.3d at 1044-45
    .        But
    the "cf." signal is a dead giveaway that the Seventh Circuit
    believed Alvarez-Cuevas did not speak directly to subpart (b)(1).
    After all, and as the Supreme Court's cases make clear, "cf." is
    "an introductory signal which shows authority that supports the
    point       in    dictum    or   by   analogy,       not    one   that   'controls'     or
    'dictates' the result."               Lambrix v. Singletary, 
    520 U.S. 518
    , 529
    (1997)      (emphasis       added).      And    because      Alvarez-Cuevas       is   not
    controlling precedent on the § 2A4.1(b)(1) issue, Romero's first
    attempt to clear the high plain-error hurdle falls short.
    With no binding precedent on his side, Romero cannot
    succeed on plain-error review unless he shows his ransom-demand
    theory is compelled by the guidelines' language itself. See, e.g.,
    
    Jones, 748 F.3d at 70
    ; 
    Caraballo-Rodriguez, 480 F.3d at 70
    .                            And
    to the extent he tries to make that argument, it fails too.
    In Reynolds — the case he hangs his hat on — the Seventh
    Circuit          candidly   acknowledged       how    "difficult"        the   issue   is,
    because the guidelines do not define "ransom" and the guidelines'
    commentary offers "no insight into what conduct the Sentencing
    Commission intends § 2A4.1(b)(1) to 
    punish."5 714 F.3d at 1044
    .
    5
    The Sentencing Commission is an agency tasked by Congress
    with issuing sentencing guidelines and keeping them current. See
    28 U.S.C. § 994.
    - 24 -
    The Seventh Circuit also rejected the ransom definition in Black's
    Law Dictionary ("Black's," for short), see 
    id. — which
    is the go-
    to dictionary for courts in figuring out the commonest legal
    meanings of terms, see generally United States v. Nason, 
    269 F.3d 10
    ,   16   (1st    Cir.    2001)    (noting    how   the   court   was   turning
    "predictably" to Black's "to glean the most widely accepted legal
    meaning" of the term at issue there (emphasis added)).                   Black's
    defines "ransom" as "[m]oney or other consideration demanded or
    paid for the release of a captured person or property," which, the
    government in Reynolds argued, could include a demand made on the
    victim himself.      
    See 714 F.3d at 1044
    (quoting Black's).             But the
    Seventh    Circuit    found    that    definition    to    be   "overinclusive"
    because under it "even a simple mugging would include a 'ransom'
    demand if at some point during the attack" the attacker "offered
    to let the victim go in exchange for her valuables or some other
    benefit."    
    Id. The Seventh
    Circuit then said that the "language of the
    guideline . . . presupposes the existence of a third party."                 
    Id. (emphasis added).
            Section 2A4.1(b)(1), the court noted, "applies
    if 'a ransom demand or a demand upon government was made.'"                  
    Id. (quoting the
    provision).           These "are distinct actions," the court
    wrote, "and yet the Sentencing Commission . . . group[s] them
    together," even though "a 'demand upon government' cannot be made
    - 25 -
    during a kidnapping without the communication of demands to people
    other than those held captive."       
    Id. And because
    "'a demand upon
    government'   cannot   be   made   during   a   kidnapping   without   the
    communication of demands to [non-captives]," the court said "that
    'ransom demand' is fairly read to also include this third-party
    element."   
    Id. Moving on,
    the Seventh Circuit then discussed potential
    policy concerns;6 noted potential parallels between the provision
    and the Hostage Taking Act ("HTA"), 18 U.S.C. § 1203;7 and mentioned
    that while "no appellate court has considered whether § 2A4.1(b)(1)
    requires the communication of demands to third parties," it had
    "not found a single appellate decision where the adjustment had
    6 "[K]idnapping someone . . . to compel others to act, as a
    substitute for confronting or attempting to rob those others in
    person," the court stated, "can be a very effective way to
    accomplish crime that merits heightened deterrence." 
    Id. But if
    this is done "without the knowledge of anyone except for the
    victim, the scope of the crime and risk of harm to others, while
    undoubtedly extensive, is nonetheless not as great." 
    Id. 7 "[T]he
    HTA," the court remarked, "punishes 'whoever . . .
    seizes or detains and threatens to kill, to injure, or to continue
    to detain another person . . . to compel a third person or a
    governmental organization to do or abstain from doing any act as
    an explicit or implicit condition for the release of the person
    detained.'"   
    Id. at 1045
    (quoting 18 U.S.C. § 1203(a)) (first
    alteration in original).     And "[g]iven the[] similarities in
    language and parallel structure," the court added, "§ 2A4.1(b)(1)
    appears to paraphrase the language of the HTA," and so the court
    "believe[d] it is meant to apply only when a kidnapper issues
    demands . . . to compel a third party (either the government or
    private citizen) to act." 
    Id. - 26
    -
    been applied to a defendant who did not intend for his demands to
    reach a third party."8
    That the Seventh Circuit judged the ransom-demand issue
    "difficult" — justifying resort to interpretative aids (including
    presupposition) — kiboshes any suggestion on Romero's part that
    the   guidelines'    words   unquestionably    support   his   position.
    Properly viewed, his ransom-demand argument ultimately "turns on
    judicial construction of the [guidelines]," and "since we have not
    yet adopted the construction he urges, there is no plain error."
    See 
    Caraballo-Rodriguez, 480 F.3d at 73
    .
    If more were needed (and it is not), the Eleventh
    Circuit, unlike the Seventh Circuit, accepts Black's definition in
    interpreting "ransom demand" in § 2A4.1(b)(1) — specifically, the
    Eleventh Circuit has held that "[n]othing in that definition
    excludes" money that the kidnapper thinks the victim owes him from
    qualifying as a "ransom demand."     See United States v. Digiorgio,
    
    193 F.3d 1175
    , 1178 (11th Cir. 1999) (per curiam).        And the Fifth
    and Second Circuits have upheld enhancements under § 2A4.1(b)(1)
    where the kidnappers demanded money or other consideration from
    the victim and not a third party.         See United States v. Andrews,
    
    503 F. App'x 257
    , 258 (5th Cir. 2012) (per curiam); United States
    8

    v. Escobar-Posado, 
    112 F.3d 82
    , 82-83 (2d Cir. 1997) (per curiam).
    In a later case, the Second Circuit specifically observed that its
    Escobar-Posado opinion "took a different approach" to the ransom-
    demand guideline than the Seventh Circuit's Reynolds opinion.   See
    United States v. Cole, 
    594 F. App'x 35
    , 38 (2d Cir. 2015) (summary
    order).   Anyhow, the different precedents on the question at hand
    preclude Romero from showing that any error (if error there was)
    was plain — which is to say, clear or obvious.9    See, e.g., United
    States v. D'Amario, 
    412 F.3d 253
    , 256–57 (1st Cir. 2005); United
    States v. Diaz, 
    285 F.3d 92
    , 97 (1st Cir. 2002).
    The bottom line:   Perhaps someday we will have to take
    a definitive stand on the ransom-demand issue.        Cf. generally
    
    Caraballo-Rodriguez, 480 F.3d at 70
    (noting that a holding that a
    party "has not met his burden of showing there was an error which
    was plain" is not a "ruling on the merits").        But for today's
    purposes, it suffices to say that Romero's ransom-demand theory is
    not the stuff of plain error.      See generally United States v.
    Frady, 
    456 U.S. 152
    , 163 (1982) (noting that plain error assumes
    9 To the extent Romero believes the government did not make —
    and thus waived — any argument on the "clear or obvious" prong, he
    is dead wrong, as the government believes Reynolds's holding does
    not help Romero demonstrate "a 'clear or obvious' error" on the
    judge's part.
    - 28 -
    an error so self-evident that the judge should have avoided it,
    "even absent the defendant's timely assistance in detecting it").
    Obstruction of Justice and Minor Role
    Romero knocks the judge for not "expressly" ruling on
    his objections to the PSR's inclusion of a 2-level obstruction-
    of-justice      enhancement       and     rejection    of   a    2-level   minor-role
    reduction.        And    he    criticizes      the     judge      for    not   properly
    calculating the sentencing range because (the theory goes) the
    record    did   not     support     the    enhancement      but    did    support    the
    reduction.      Agreeing with Romero that the judge did not explicitly
    rule on his two targeted objections, the government counters that
    his protests "were inconsequential to the proper calculation" of
    the sentencing range.          The government also argues that the record
    "amply support[s]" the judge's denial of his objections.                       For our
    part, regardless of the applicable standard of review — the
    government sometimes talks about plain error, and Romero talks
    about abuse of discretion — we see no need for a sentencing do-
    over.
    Take Romero's first beef.               We agree with the parties
    that    the   judge     did   not   expressly      rule     on   his    objections    at
    sentencing (though the judge arguably addressed Romero's minor-
    role-reduction request at sentencing when he said he "agree[ed]
    with the government's characterization that . . . Romero's role
    - 29 -
    was very important in the organization").    But that gets Romero
    only so far.
    Sentencers, of course, "must — for any disputed portion
    of the [PSR] or other controverted matter — rule on the dispute or
    determine that a ruling is unnecessary either because the matter
    will not affect sentencing, or because [they] will not consider
    the matter in sentencing."     Fed. R. Crim. P. 32(i)(3)(B).   Our
    preference is for judges to make reasonably explicit rulings on
    properly disputed matters.    See, e.g., United States v. Van, 
    87 F.3d 1
    , 3 (1st Cir. 1996).   But the lack of an explicit ruling is
    not always catastrophic.     United States v. Carbajal-Váldez, 
    874 F.3d 778
    , 783 (1st Cir. 2017).    Our case law allows us to uphold
    sentencing conclusions if the judges "implicitly resolved" the
    disputes, like when their "statements and the sentence[s] imposed
    show[] that the [disputes] were decided in a particular way." 
    Van, 87 F.3d at 3
    (emphasis added); see also United States v. Zehrung,
    
    714 F.3d 628
    , 632 (1st Cir. 2013).
    Returning to our case, we see that the judge started the
    sentencing hearing by saying that he read the PSR and the parties'
    sentencing memos. Which means he knew that (a) the PSR recommended
    a sentencing range of 360 months to life, a range driven in part
    by a rejection of Romero's obstruction-of-justice/minor-role-based
    objections; that (b) Romero wanted a 120-month sentence; and that
    - 30 -
    (c) the government wanted a 312-month sentence.                 Saying he was
    "not sure" if Romero's objections mattered — because, as he saw
    it, the government's asked-for sentence was "below" what Romero
    would get if he resolved the objections in Romero's favor — the
    judge then had the lawyers flesh out their "approach to the case"
    and their "recommendation."         So the lawyers talked a lot to the
    judge about Romero's role in the conspiracy and whether he had
    obstructed justice.      Ultimately, however, in selecting a 276-month
    sentence (a term even lower than the below-guidelines sentence the
    government recommended), the judge adopted the PSR (emphasis ours)
    "without change" — i.e., he accepted the PSR's sentencing-range
    calculations, including its rejection of Romero's obstruction-of-
    justice/minor-role-based protests.           This we know because of the
    judge's written statement of reasons.              So the record read as a
    whole "reliably shows" that the judge implicitly resolved Romero's
    objections against him.       See 
    Carbajal-Váldez, 874 F.3d at 783-84
    .
    Which suffices to reject his no-express-ruling argument.             See id.;
    see also United States v. Zayas-Ortiz, 
    808 F.3d 520
    , 523-24 (1st
    Cir. 2015) (rejecting a defendant's claim that the lower court did
    not   "give   sufficient     reasons   for   its    decision"    denying   his
    sentence-reduction motion, our rationale being that the court had
    checked   a   box   on   a   form   indicating     it   had   considered   the
    appropriate policy statements and sentencing factors, and we could
    - 31 -
    infer the denial's basis by comparing what the parties argued with
    what the court did).
    As for Romero's second argument — that the record does
    not back the obstruction-of-justice increase but does back the
    minor-role decrease — even less need be said. With a total-offense
    level of 42 and a criminal-history category of VI, Romero had a
    sentencing range of 360 months to life.          Granting him a 2-level
    minor-role reduction and jettisoning the 2-level obstruction-of-
    justice enhancement would drop his total-offense level to 38 (a
    number that includes the ransom-demand enhancement, which, as we
    said, survives plain-error review).         Combined with the same VI
    criminal-history category, Romero's sentencing range would remain
    360 months to life.        See USSG Ch. 5, Pt. A (sentencing table).
    Thus any error (if there was one) in resolving Romero's objections
    against him provides no basis for upsetting the sentence.                See
    United States v. Hinkley, 
    803 F.3d 85
    , 93-94 (1st Cir. 2015)
    (finding no reason to vacate a defendant's sentence because even
    if the contested "enhancement were removed, the guideline sentence
    would be unchanged" — which means "any error in the application of
    this   enhancement   was    harmless");   see   also   United   States    v.
    Monteiro, 
    871 F.3d 99
    , 115 n.15 (1st Cir. 2017) (declining to
    consider an argument about an enhancement because fixing any error
    would not change defendant's sentence), cert. denied, 2018 WL
    - 32 -
    1278424 (2018); cf. United States v. Sepulveda, 
    15 F.3d 1161
    , 1199
    (1st Cir. 1993) (stating that "[i]t is unnecessary to address an
    allegedly erroneous sentencing computation if, and to the extent
    that, correcting it will not change the applicable offense level
    or   otherwise     influence        the    defendant's"   sentencing      range   and
    (thus) his sentence); United States v. Carrozza, 
    4 F.3d 70
    , 88
    (1st Cir. 1993) (explaining that courts have "inherent power not
    to decide disputes that are immaterial or irrelevant to the
    ultimate sentence").
    Enough     said       about   Romero's    procedural-reasonableness
    challenge.       On then to his substantive-reasonableness challenge.
    Substantive Reasonableness
    Romero separately argues that his 276-month sentence is
    substantively unreasonable (or too long, in everyday speech) — a
    multifaceted claim based on his belief that the judge, first,
    wrongly    hit    him   with       an     obstruction-of-justice    increase      and
    unfairly     withheld          a     minor-role       decrease,    and,     second,
    "unjustifiably" picked a term "more severe than those of more
    culpable defendants in the instant case and than those sentences
    imposed nationally at the median for this offense."                 Reviewing his
    claim for abuse of discretion, see 
    Tanco-Pizarro, 892 F.3d at 483
    ,
    we detect none.
    - 33 -
    Romero's argument about the obstruction-of-justice and
    minor-role adjustments is simply a repackaged version of the one
    just rejected.    And it fails for reasons already given.
    Romero's next contention — that the 276-month sentence
    created an unwarranted sentencing disparity between himself and
    his codefendants — is not without some surface appeal.                   But it
    cannot be sustained.
    Sentencers, no doubt, must consider "the need to avoid
    unwarranted sentence disparities among defendants with similar
    records who have been found guilty of similar conduct."                18 U.S.C.
    §   3553(a)(6).     The    key   word    is   "unwarranted"       —   that   is,
    § 3553(a)(6) does not ban all disparities, just "unwarranted"
    ones.     Anyway,    the     statute's    main   concern     is       minimizing
    "national[]"    sentencing    disparities     among   like    criminals      who
    commit like crimes.    See United States v. Martin, 
    520 F.3d 87
    , 94
    (1st Cir. 2008).     Even so, our cases recognize that "legitimate
    concerns may arise" if a judge sentences "similarly situated
    coconspirators or codefendants" to "inexplicably disparate" terms.
    See United States v. Demers, 
    842 F.3d 8
    , 15 (1st Cir. 2016); see
    also United States v. Correa-Osorio, 
    784 F.3d 11
    , 28 n.25 (1st
    Cir. 2015).    But — and it is a big "but" — our cases also recognize
    that such a disparity claim will flop "if material differences
    between the defendant and the proposed comparator[s] suffice to
    - 34 -
    explain the divergence."       
    Demers, 842 F.3d at 15
    .          And by material
    differences      our   cases   mean    things     like   dissimilar     criminal
    involvement,       criminal    histories,       or   cooperation      with   the
    government, to name just a few.                See United States v. Flores-
    Machicote, 
    706 F.3d 16
    , 24 (1st Cir. 2013).
    Yes, Guzman, Maldonado, Wallace, Reynoso, and Matos all
    received sentences considerably less than 276 months.                 But unlike
    Guzman, Maldonado, Wallace, and Reynoso, Romero did not cooperate
    with the government.      And unlike Matos, Romero abducted Amparo and
    Castro    at    gunpoint.10    These    differences      make   the   sentencing
    disparities reasonable.11       See, e.g., United States v. Mueffelman,
    
    470 F.3d 33
    , 41 (1st Cir. 2006) (discussing cooperation); United
    States v. Reverol-Rivera, 
    778 F.3d 363
    , 366 (1st Cir. 2015)
    10 Citing a statement in the PSR that Matos was "part of the
    team that kidnapped [the victims] on July 23, 2012," Romero asserts
    that the evidence concerning Matos's role is "unclear at best."
    But despite his best efforts, we see nothing inconsistent between
    that statement and descriptions later in the PSR suggesting that
    Matos's role as part of that team was limited to attaching a GPS
    device and storing uniforms and weapons.
    11Romero concedes, as he must, that a sentencing difference
    is not a forbidden disparity if justified by a legitimate
    consideration, like rewarding cooperation.     But he thinks this
    principle does not apply here because, in his words, prosecutors
    opted to let "defendants who were among the most culpable to
    cooperate against lower members of the organization." Romero rests
    his theory on pure speculation, not case analysis. And so we say
    no more about it. See Muñiz v. Rovira, 
    373 F.3d 1
    , 8 (1st Cir.
    2004) (holding waived a skeletal argument unaccompanied by
    "citation to any pertinent authority"); United States v. Zannino,
    
    895 F.2d 1
    , 17 (1st Cir. 1990) (same).
    - 35 -
    (discussing culpability).       Also hurting Romero is his failure to
    present info about his co-conspirators' criminal histories, info
    we need so we can see if "he and his proposed comparators are
    similarly situated."        See United States v. Rodríguez-Adorno, 
    852 F.3d 168
    , 177 (1st Cir.), cert. denied, 
    138 S. Ct. 163
    (2017).
    Trying to avoid the inevitable result of this reasoning,
    Romero argues that any dissimilarities between him and his co-
    conspirators should not matter, thanks to United States v. Reyes-
    Santiago, 
    804 F.3d 453
    (1st Cir. 2015).                But Reyes-Santiago is
    easily   distinguishable      from    our   own     case.     Reyes-Santiago's
    sentence    reflected   an   unwarranted       disparity     for    two   reasons.
    First,     the   district    court   did      not   accept    his    drug-amount
    stipulation but did accept his co-defendants', without offering
    any rationale to "justif[y] the uniquely harsh approach" in picking
    his sentence." 
    Id. at 468-73;
    see generally United States v. Ramos
    Diaz, 
    702 F. App'x 1
    , 3 n.3 (1st Cir. 2017) (explaining that Reyes-
    Santiago "involved a Sentencing Guidelines factor — drug quantity
    — that was applicable to all of the defendants and was applied
    uniquely harshly to the appellant").                And second, the district
    court considered info that Reyes-Santiago had participated in a
    "massacre" after saying it would "not . . . factor the murders
    into the defendants' sentences for the drug conspiracy."                   Reyes-
    - 36 -
    
    Santiago, 804 F.3d at 473
    .       Nothing like that happened here,
    however.
    That leaves us with Romero's suggestion of a disparity
    between his sentence and the sentences of similarly situated
    defendants across the country.     The problem for him is that he
    floats this suggestion in the "Summary of Argument" section of his
    brief and then never gives it the sort of treatment needed to
    preserve the point for appellate review.     For instance, he does
    not give us the necessary info about the other defendants — their
    criminal involvement, their criminal histories, their cooperation
    (or not) with the government, etc. — to do an "apples to apples"
    comparison.     See 
    Rodríguez-Adorno, 852 F.3d at 177
    (emphasizing
    that "[a] credible claim of sentencing disparity requires that the
    proponent furnish . . . enough relevant information" so that "the
    court [can] compare apples to apples" (internal quotation marks
    omitted)).      So we deem the suggestion waived by perfunctory
    treatment.     See United States v. Pérez, 
    819 F.3d 541
    , 547 (1st
    Cir. 2016); United States v. Pérez-Mejílas, 
    292 F. App'x 69
    , 70
    (1st Cir. 2008).
    WRAP UP
    Having worked our way through the issues, we affirm
    Romero's sentence.
