    DYK, Circuit Judge.           Carlos Enrique López-Soto appeals
    convictions and sentences imposed by the United States District
    Court for the District of Puerto Rico for three Hobbs Act robberies
    under 18 U.S.C. § 1951, two counts of brandishing a firearm during
    and   in    relation   to    a     crime        of        violence      under       18        U.S.C.
    § 924(c)(1)(A)(ii), two counts of possession of a firearm by a
    convicted felon under 18 U.S.C. §§ 922(g)(1) and 924(a)(2), one
    count of possession of ammunition by a convicted felon under 18
    U.S.C. §§ 922(g)(1) and 924(a)(2), and conspiring to commit a
    Racketeer     Influenced     and    Corrupt           Organizations           Act        ("RICO")
    violation under 18 U.S.C. §§ 1962(d) and 1963(a).                             We affirm the
    convictions and sentences except that we remand for the limited
    purpose of reducing López-Soto’s sentence for the Hobbs Act and
    RICO counts to the 240-month statutory maximum.
    I.
    López-Soto     was    alleged           to    be    part    of     a    group        --
    consisting     of   himself,      Luis     Ruiz-Santiago             ("Ruiz"),            Roberto
    García-Santiago     ("García"),       and        Jesús          Ramírez-Cotto            --    that
    conducted a string of robberies in 2014.                             Two robberies were
    conducted with García (on May 23, 2014 and June 3, 2014), and one
    was with García and Ruiz (on May 17, 2014).
    On October 22, 2014, a Grand Jury returned a superseding
    indictment in Case No. 14-cr-415 charging López-Soto with: (1)
    - 3 -
    Hobbs Act robbery under 18 U.S.C. §§ 1951 and 2 (Count One); (2)
    brandishing a firearm during and in relation to a crime of violence
    under   18   U.S.C.    §§ 924(c)(1)(A)(ii)   and   2   (Count    Two);   (3)
    possession of a firearm by a convicted felon under 18 U.S.C.
    §§ 922(g)(1), 924(a)(2), and 2 (Count Three); and (4) possession
    of ammunition by a convicted felon under 18 U.S.C. §§ 922(g)(1)
    and 924(a)(2) (Count Four).         The same day, a Grand Jury returned
    an indictment charging López-Soto with: (1) conspiring to commit
    a Racketeer Influenced and Corrupt Organizations Act ("RICO")
    violation under 18 U.S.C. § 1962(d) (Count One); (2) Hobbs Act
    robberies under 18 U.S.C. §§ 1951 and 2 (Counts Fourteen and
    Fifteen); (3) brandishing a firearm in relation to a crime of
    violence     under    18   U.S.C.   §§ 924(c)(1)(A)(ii)    and   2   (Count
    Sixteen); and (4) possession of a firearm by a convicted felon
    under 18 U.S.C. §§ 922(g)(1), 924(a)(2), and 2 (Count Seventeen).
    All were aiding and abetting charges except for the RICO charge
    and the charge for possession of ammunition.           The two cases were
    consolidated and both were tried together starting on December 1,
    2016.
    López-Soto was represented by counsel until the time of
    trial, but he represented himself at trial.               García and Ruiz
    cooperated with the government and testified as to López-Soto's
    participation in the robberies and other offenses for which he was
    charged.     The government also presented evidence (1) of video
    - 4 -
    recordings of the robberies, one of which appeared to show López-
    Soto at the scene; (2) that López-Soto was arrested wearing a
    striped shirt similar to the shirt worn by one of the perpetrators
    of a May 23, 2014, robbery, and that ammunition seized from López-
    Soto was of the same caliber as that of the revolver used in the
    robberies;    (3)   that    López-Soto        owned   and    was    arrested       in   a
    burgundy-colored Dodge Durango, which matched the vehicle used in
    the robberies, and that, in López-Soto's presence, his colleagues
    had attempted to spray paint the Durango black a day after the
    June 3, 2014 robbery; and (4) that boxes of cell phones and
    accessories    were      seized    by   the     government    from        López-Soto's
    girlfriend's apartment, including a box with the label of a cell
    phone store that had been robbed.
    The jury convicted López-Soto on all counts.                   The court
    sentenced López-Soto to 360 months as to Count One in Case No. 14-
    cr-415, and as to Counts One, Fourteen, and Fifteen in Case No.
    14-cr-637,     to   be    served    concurrently       with        each    other    but
    consecutively to an imprisonment term of 84 months as to Counts
    Two, Three, and Four in Case No. 14-cr-415, and Count Seventeen in
    Case No. 14-cr-637, and consecutively to 300 months of imprisonment
    as to Count Sixteen in Case No. 14-cr-637.1                 The sentence results
    in a total imprisonment term of 744 months (62 years).
    1The Judgement in Case No. 14-cr-637 lists the conviction as
    to Count Seventeen as corresponding to "18 U.S.C. § 924(g)(1) &
    - 5 -
    López-Soto appeals.       He filed two sets of briefs: an
    opening and a reply brief prepared by his counsel, and a pro se
    brief.    We have jurisdiction under 28 U.S.C. § 1291 to review the
    final decisions of the district court, and under 18 U.S.C. § 3742
    to review the district court's sentence.
    II.
    A.
    We   first   address    López-Soto's    contention   that   the
    district court improperly instructed the jury as to the medical
    care to which cooperating co-defendant Ruiz was entitled.             López-
    Soto also contends that, in providing this instruction, the judge
    indicated     bias.       The    instruction   was   given   during   Ruiz's
    testimony.    Some background is useful.
    Ruiz was arrested on October 29, 2014, and, like López-
    Soto, charged with Hobbs Act robbery, RICO, and firearm-related
    offenses.    On November 10, 2014, at his arraignment, Ruiz pled not
    guilty.
    However, on April 6, 2015, Ruiz signed a plea agreement
    with the government.            Ruiz agreed to plead guilty to a RICO
    violation and the carrying of a firearm during and in relation to
    a crime of violence, and the government agreed to dismiss all other
    924(a)(2)." This appears to be a typographical error. As noted
    above, Count Seventeen corresponds to 18 U.S.C. §§ 922(g)(1),
    924(a)(2), and 2.
    - 6 -
    charges.   As part of the plea agreement, Ruiz stipulated that he
    led a criminal organization that committed robberies, and listed
    fourteen robberies conducted by the organization between November
    12, 2013, and June 3, 2014.        Ruiz further stated in the plea
    agreement that López-Soto took part in five of these robberies,
    which occurred on or about May 4, May 17, May 23, and June 3, all
    in 2014.   On June 11, 2015, the district court accepted Ruiz's
    guilty plea.
    On June 30, 2015, about 18 months before López-Soto's
    trial, Ruiz, acting pro se, filed a motion to withdraw his guilty
    plea.   In a three-page handwritten document, Ruiz asserted that
    he pled guilty based on his counsel's representation that he would
    not receive medical treatment unless he accepted the government's
    plea agreement.      Ruiz claimed that because his medical condition
    at the time was "critical" -- he continued to suffer from being
    shot in another incident fourteen years earlier -- his guilty plea
    was   involuntary.      Specifically,    Ruiz   asserted   that   he   only
    accepted the plea offer because his attorney told him that he would
    not get the medical treatment he needed otherwise.          He requested
    that he be allowed to withdraw his plea and that he be assigned
    new counsel for trial.      The district court denied Ruiz's motion,
    explaining that "[Ruiz's] plea has been accepted by the court.
    More so, the present motion [to withdraw his guilty plea] prepared
    - 7 -
    by   a   jailhouse   lawyer,   and    not    [Ruiz's]   counsel    . . .,   is
    perfunctory and generic."
    Thereafter, Ruiz appeared as a government witness at
    López-Soto's trial, testifying as to López-Soto's involvement in
    the planning and execution of the robberies for which he was
    charged.
    López-Soto sought to attack Ruiz's trial testimony by
    showing that Ruiz believed he would not receive medical care for
    his gunshot injuries unless Ruiz agreed to the government's plea
    deal.    López-Soto asked Ruiz:
    And it would be accurate to say that you also
    express in that document to this Court [i.e.,
    Ruiz's motion to withdraw his guilty plea],
    sir, that you were going to accept this offer
    [i.e., the plea agreement] due to the pain and
    suffering that you have to deal with in the
    facility at MDC Guaynabo due to the fact that
    you were shot several times and went through
    so many surgeries and have a critical health?
    Yes or no.
    Before Ruiz answered, the court called for a sidebar.             At sidebar,
    the court stated:
    Now I'm forced to give an instruction. And
    the instruction is that he's entitled to that
    [i.e., medical treatment], plea or not plea.
    Because that is a right that the defendant has
    by law, plea or not plea; the right to receive
    medical treatment.
    Then, in open court, the court instructed the jury ("the medical
    care instruction") over López-Soto's objections, stating:
    - 8 -
    THE COURT: So the jury is not confused, all
    defendants, plea or not plea, are entitled by
    law to the following: To provide the defendant
    with the needed educational or vocational
    training, medical care, or other correctional
    treatment in the most effective manner. All
    defendants. All. All of them are entitled
    to that, plea or not plea. So if you want to
    continue under this chain of thought, he is
    entitled medical care.     Period.   After he
    leaves MDC Guaynabo, he's entitled to that. In
    fact, he may have received already some of
    that treatment if he's living outside MDC
    Guaynabo.
    MR. LÓPEZ-SOTO: But, Your Honor.
    THE COURT: Don't argue with me. That's the
    law. So that they're not confused, they are
    getting the law now.
    MR. LÓPEZ-SOTO: Okay, Your Honor. But I have
    an objection to that, Your Honor.
    THE COURT: You may have many objections, but
    you asked those questions, and you're leaving
    this jury in doubt whether or not the matter
    was going to be accepted or not based strictly
    on a quid pro quo of the medical treatment.
    When he, by law, is entitled that. By law. It
    doesn't go with the plea agreement. You won't
    find that in the plea agreement either. It's
    not there. Because he's entitled by law to
    receive that.     You decided to ask these
    questions. And now the jury was confused
    thinking that that would be a quid pro quo.
    That cannot be a quid pro quo.
    Keep on asking [your questions].
    After this instruction, in response to further questioning by
    López-Soto, Ruiz testified that he signed the agreement "without
    any promise."
    - 9 -
    On appeal, López-Soto argues that the district court's
    medical care instruction was improper and that the instruction is
    evidence of bias by the trial judge.           We reject the claim of bias
    but agree that the district court's medical care instruction was
    improper.     We nevertheless conclude that this error was harmless
    in light of the overwhelming evidence of López-Soto's guilt.
    This court has recognized that trial judges have a
    "common law power to question witnesses and to analyze, dissect,
    explain, summarize, and comment on the evidence."            Logue v. Dore,
    
    103 F.3d 1040
    , 1045 (1st Cir. 1997).           "What a trial judge may not
    do, however, is take on the role of an advocate or 'otherwise use
    his     judicial     powers   to   advantage   or   disadvantage   a     party
    unfairly.'"        United States v. Ayala-Vazquez, 
    751 F.3d 1
    , 24 (1st
    Cir. 2014) (quoting 
    Logue, 103 F.3d at 1045
    ).               "In that vein,
    there is no question that it is 'improper for a judge to assume
    the role of a witness' by testifying to facts or authenticating
    evidence."
    Id. (quoting Glasser
    v. United States, 
    315 U.S. 60
    ,
    82 (1942)).        When addressing allegations of judicial bias, this
    court     considers     (1)   "whether   the    [judge’s]   comments      were
    improper"; and, if so, (2) "whether the complaining party can show
    serious prejudice."       United States v. DeCologero, 
    530 F.3d 36
    , 56
    (1st Cir. 2008).
    Although    we   do   not   conclude   that    López-Soto    has
    established that the trial judge was biased, the impropriety of
    - 10 -
    the district court's medical care instruction is evident.                    The
    district court's instruction purported to be a statement of law,
    but it was in reality a factual representation that Ruiz had an
    unconditional right to medical care, and strongly implied that
    Ruiz could not have been concerned about receiving adequate medical
    care.    It also suggested that López-Soto's line of questioning was
    unsupported and improper.        The district court's instruction thus
    added to the record evidence.          In doing so, the district judge
    failed to heed this court's guidance that "trial judges must guard
    against adding to the evidence . . . under the guise of . . .
    commenting on the evidence."        
    Ayala-Vazquez, 751 F.3d at 28
    ; see
    also    Quercia   v.   United   States,   
    289 U.S. 466
    ,    471–72   (1933)
    (ordering the reversal of a judgment where "the trial judge did
    not analyze the evidence; he added to it, and he based his
    instruction [to the jury] upon his own addition").
    The instruction cannot be justified as correcting a
    factual error as to Ruiz's legal right to medical care.             The issue
    was not whether Ruiz would have been legally entitled to medical
    care if he had not signed the plea agreement, but instead whether
    Ruiz believed he had to agree to the plea deal in order to receive
    care.      The    district   judge's   instruction     had    the   effect   of
    eliminating from the jury's consideration this salient factual
    issue.     Not only did the trial judge prevent López-Soto from
    pursuing this impeachment theory, the judge contradicted it by
    - 11 -
    suggesting that Ruiz could not have been motivated by his need to
    secure medical care.           The impropriety of the instruction is
    especially apparent where, as here, the prosecution had neither
    objected    to   López-Soto's     line       of    questioning    nor    sought   a
    corrective instruction from the court.
    Notwithstanding this error, we do not order a new trial
    because    López-Soto   has    not    met    his    burden   to   show   "serious
    prejudice."      See 
    DeCologero, 530 F.3d at 56
    .                  It is, first,
    unclear whether, absent the instruction, Ruiz's testimony would
    have been helpful to López-Soto.            As the district judge noted, the
    terms of Ruiz's plea agreement stated that "[t]he United States
    has made no promises or representations except as set forth in
    writing in this Plea Agreement and deny [sic] the existence of any
    other term and conditions not stated herein."                     On cross, Ruiz
    testified that he signed the agreement "without any promise."                 And
    on re-direct, Ruiz distanced himself from his motion to withdraw,
    testifying that he did not actually write the motion and only
    "signed it under fear" that he would suffer adverse consequences
    if he did not sign it.        And Ruiz never suggested -- whether in his
    motion to withdraw or elsewhere -- that his statements regarding
    López-Soto's     involvement     in    the    offenses    were    false.      This
    evidence    suggests    that    López-Soto's        questioning     (absent   the
    improper medical care instruction) was unlikely to be helpful to
    López-Soto.
    - 12 -
    Even     if     Ruiz's    testimony     had    been    successfully
    impeached, the other evidence of López-Soto's guilt (described
    above) -- including testimony by cooperating co-defendant García-
    Santiago, video recordings, items seized from López-Soto and his
    girlfriend, and other physical evidence connecting López-Soto to
    the robberies -- was overwhelming.              In light of this evidence,
    "[w]e are satisfied that 'there is no chance that the remarks made
    [by the district judge] prejudiced the outcome' of the trial."
    See 
    Ayala-Vazquez, 751 F.3d at 27
    (quoting United States v.
    Gentles, 
    619 F.3d 75
    , 83 (1st Cir. 2010)).
    B.
    We     next     address   López-Soto's    contention     that   the
    district court erred in preventing him from cross-examining Ruiz
    about Ruiz's testimony that López-Soto participated in robberies
    occurring     in     2013,     in   violation   of    the   Sixth   Amendment's
    Confrontation Clause.           The district court had prevented cross-
    examination on the basis that López-Soto was not charged with 2013
    robberies.
    Before Ruiz testified, the government had called the
    other cooperating co-defendant, García.               On direct examination,
    García testified that López-Soto committed robberies in 2013:
    Q. And going to those robberies in 2013, with
    whom did you commit these robberies that
    you're talking to us about?
    A. With the gentleman that's here.
    - 13 -
    Q. And who are you referring to, sir?
    . . . .
    A. Chemito [i.e., López-Soto].
    On cross-examination, García reiterated López-Soto's participation
    in 2013 robberies:
    Q. . . . In what month of 2013 I sold you the
    revolver, .38 caliber, and we get together and
    plan all this?
    A. It was around, like, May or June. We would
    meet in that business establishment Flor de
    Mayo. Luis, Chemito would meet there with me.
    I would bring Coco, Juvencio, Juve, and
    myself. Yeah.
    . . . .
    BY MR. LÓPEZ-SOTO:
    Q. Can you specify a month in 2013 that I
    participate in any robbery with you?
    A. I don't recall exactly like that in 2013,
    a month.
    Q. But you remember it was in 2013?
    A. That's right. That's correct.
    (emphasis added).    The district court imposed no limit on the
    cross-examination.
    Later when Ruiz took the stand he testified as to López-
    Soto's   participation   in   robberies.   On   questioning   from   the
    government, Ruiz stated:
    - 14 -
    Q. Did it come a time that you engaged in
    robberies, sir?
    A. Yes.
    . . . .
    Q. And when was this, sir?
    A. Well, in 2013. Well, or 2013, 2014. On or
    about that time.
    . . . .
    Q. And, sir, you mentioned to us that around
    2013, 2014 you did robberies.
    A. Correct.
    Q. With whom did you do these robberies?
    . . . .
    A. With . . . Chemito [i.e., López-Soto].
    (emphasis added).
    On cross-examination, López-Soto sought to discredit
    Ruiz by getting him to admit that López-Soto had not participated
    in any robberies in 2013.      To that end, López-Soto asked Ruiz the
    date in 2013 on which they first met.           Before Ruiz answered, the
    prosecutor objected.       The prosecutor reasoned that López-Soto did
    not have a "good-faith basis" for asking the question because he
    "knows that he participated [only] in 2014, that's why he cannot
    coax the witness [into testifying that they that met or committed
    robberies]     in   2013."      The   district     court   sustained    the
    government's    objection,    explaining   to    López-Soto   that   "[y]ou
    - 15 -
    cannot . . . coax the witness to give a wrongful answer and then
    say that he's a liar," and that "[y]ou're not charged with anything
    in 2013.    Nothing."       As a result, López-Soto was not allowed to
    cross-examine     Ruiz   as    to     López-Soto's     involvement       (or    lack
    thereof) in robberies in 2013.
    López-Soto        asserts     that     the        district      court's
    restrictions     violated     his    rights    under   the    Sixth   Amendment's
    Confrontation Clause.         "The Sixth Amendment to the Constitution
    guarantees the right of an accused in a criminal prosecution 'to
    be confronted with the witnesses against him.'"                 Davis v. Alaska,
    
    415 U.S. 308
    , 315 (1974).           The right to confrontation includes the
    right to challenge the credibility of those witnesses.                      See
    id. at 318.
       A   district     court's     limitation     on    cross-examination
    violates the Confrontation Clause if, "absent the limitation,
    . . . the jury [would] have received a 'significantly different
    impression' of the witness's credibility."               DiBenedetto v. Hall,
    
    272 F.3d 1
    , 10 (1st Cir. 2001) (quoting Delaware v. Van Arsdall,
    
    475 U.S. 673
    , 680 (1986)).
    We   conclude     that     López-Soto's      Confrontation         Clause
    rights were not violated.           Ruiz's testimony at issue was cursory
    and hardly clear, in contrast to the earlier García testimony.
    The most reasonable interpretation of Ruiz's testimony was simply
    that   he   himself   was     unclear    about   the    date    of    the   charged
    robberies, rather than that López-Soto had engaged in additional,
    - 16 -
    uncharged robberies in 2013.              Allowing the testimony to stand
    (without     cross-examination)        did    not   reasonably    create       an
    impression that López-Soto committed other, uncharged robberies.
    In other words, Ruiz's testimony as to López-Soto's involvement in
    "2013,     2014"   --    even    absent    cross-examination     --    was     not
    prejudicial to López-Soto.
    In any event, even interpreting Ruiz's testimony to be
    that López-Soto participated in robberies in 2013, that testimony
    was inconsequential relative to Ruiz's testimony as a whole.                    A
    defendant’s Confrontation Clause right "is not without limits,"
    and "the district court wields considerable discretion to impose
    'reasonable    limits'     on    cross-examination."     United       States   v.
    Casey, 
    825 F.3d 1
    , 24 (1st Cir. 2016) (quoting United States v.
    Raymond, 
    698 F.3d 32
    , 40 (1st Cir. 2012)).             "The court need not
    permit unending excursions into each and every matter touching
    upon veracity if a reasonably complete picture [of a witness] has
    already been developed."          United States v. Fortes, 
    619 F.2d 108
    ,
    118 (1st Cir. 1980).            Ruiz's testimony, which spanned over two
    days and dozens of pages in the trial transcript, easily provided
    the jury with a reasonably complete picture of his "veracity, bias,
    and motivation."        See United States v. Capozzi, 
    486 F.3d 711
    , 723
    (1st Cir. 2007) (quoting United States v. Byrne 
    435 F.3d 16
    , 21
    (1st Cir. 2006)).
    - 17 -
    Ruiz testified that he had entered into a cooperation
    agreement with law enforcement, and that he had done so "to help
    [him] out with [his] sentencing and to start out anew, from zero.
    Be a good citizen."           Ruiz testified that he "would face an
    additional charge" if he did not "comply with the conditions of
    [his] cooperation [agreement]."           And López-Soto elicited testimony
    from Ruiz that tended to undercut Ruiz's credibility, for example,
    that Ruiz initially claimed to not recognize López-Soto.                    We
    cannot conclude that, absent the cross-examination that López-Soto
    sought, the jury lacked a "reasonably complete picture" of Ruiz's
    credibility, see 
    Capozzi, 486 F.3d at 723
    , or that if the district
    court had not limited López-Soto's cross-examination the jury
    would have had a "significantly different impression" of Ruiz's
    credibility, see Van 
    Arsdall, 475 U.S. at 680
    .          López-Soto's right
    to confront the witnesses against him was not violated.
    López-Soto     does       not     argue   that,   aside    from    a
    Confrontation Clause violation, the district court abused its
    discretion.    We find no error as to the district court's limitation
    of López-Soto's cross-examination.
    C.
    We    next   turn    to   López-Soto's     contention     that    the
    government violated Brady v. Maryland, 
    373 U.S. 83
    (1963), by
    failing to timely disclose materials pertaining to an interview of
    co-defendant Ruiz by law enforcement on the day of his arrest.              In
    - 18 -
    that interview, Ruiz had been shown several photographs and been
    asked to identify the person in each photograph.           Ruiz identified,
    among others, co-defendants García and Juvencio Correa-Morales.
    However, when shown a photograph of López-Soto, Ruiz "said that
    [he] didn't know him."          We review the district court's decision
    on López-Soto's Brady claim for abuse of discretion.             See United
    States v. Villarman-Oviedo, 
    325 F.3d 1
    , 13 (1st Cir. 2003).
    Although López-Soto received a report of this interview
    ("ROI")2 before trial, the government did not provide López-Soto
    with the photographs associated with the ROI until the fourth day
    of López-Soto's trial.           Without these photographs, López-Soto
    could not have known that Ruiz's statement in the ROI that he did
    not recognize the subject of the photograph was referring to López-
    Soto.         The   district   court   recognized   the   tardiness   of   the
    government's disclosure, and first offered a trial continuance
    when López-Soto complained about the late disclosure.             The court
    asked: "how much more time [in addition to the day being provided]
    do you want?"        López-Soto did not respond to the question.           The
    district court found that the delay could be sufficiently remedied
    2   It appears that the ROI is not in the record.
    The government had attempted to video record the interview,
    but it seems that due to a technical problem no recording was
    actually made. López-Soto attempted to present evidence of the
    loss of this recording to the jury, but the district court excluded
    the evidence as merely collateral. López-Soto does not challenge
    the district court's decision on this point.
    - 19 -
    by allowing López-Soto to use the ROI in trial the following day.
    The court stated: "It [the disclosure of the photographs] may have
    been late, but it [the delay] is easily cured by giving him time.
    Because he now knows, if he didn't know, that is the photograph"
    of López-Soto presented to Ruiz.                The following day López-Soto
    elicited testimony from Ruiz that when he was shown the photograph
    of López-Soto, Ruiz had stated that he "did not know him."                        On
    appeal,     López-Soto      asserts    that      the    government's    delay     in
    disclosing these photographs warrants vacatur of his convictions
    and remand for a new trial.
    "In a criminal case, [under Brady,] the government bears
    an     'affirmative      duty   to    disclose     evidence    favorable    to     a
    defendant.'"        United States v. Montoya, 
    844 F.3d 63
    , 71 (1st Cir.
    2016) (quoting Kyles v. Whitley, 
    514 U.S. 419
    , 432 (1995)).                      "If
    the government fails disclose this so-called Brady material in a
    timeous manner, the defendant may be entitled to relief."
    Id. To show
       that    a   delayed     disclosure    of      information    violated    the
    government's Brady obligation, the defendant has a "threshold
    burden"    to    "show   that    'learning      the    information    altered    the
    subsequent defense strategy, and [that], given timeous disclosure,
    a more effective strategy would likely have resulted.'"                     United
    States v. Lemmerer, 
    277 F.3d 579
    , 588 (1st Cir. 2002) (alteration
    in original) (quoting United States v. Devin, 
    918 F.2d 280
    , 290
    (1st Cir. 1990)).
    - 20 -
    López-Soto has not satisfied his threshold burden to
    show prejudice caused by the delayed disclosure.             After having
    been provided the photographs with a day to prepare, López-Soto
    was able to demonstrate that Ruiz had previously claimed not to
    know López-Soto.    López-Soto fails to explain how he would have
    done   things   differently   had    the   photographs   been    disclosed
    earlier.    In his briefing, López-Soto argues that "[i]t is hard
    to think of anything more favorable or potentially exculpatory"
    than evidence suggesting that Ruiz did not know López-Soto.            But
    this argument goes to materiality, not López-Soto's burden to show
    that "a more effective [trial] strategy" would have resulted from
    an earlier disclosure. See 
    Lemmerer, 277 F.3d at 588
    .             At oral
    argument,    López-Soto   could     only   provide   "the    obvious   but
    admittedly generic answer that the appellant would have been better
    prepared for trial" with an earlier disclosure.             But López-Soto
    "'must bear the burden of producing, at the very least, a prima
    facie showing of a plausible strategic option which the delay
    foreclosed' . . . or [how the delay] prevented defense counsel
    from using [the evidence]     effectively."
    Id. (quoting Devin,
    918
    F.2d at 290).    López-Soto has not met his burden.
    D.
    López-Soto argues that his motion to suppress should not
    have been denied and that the evidence at trial was insufficient
    to convict him.
    - 21 -
    1
    Although the district court granted López-Soto's motion
    to suppress his confession made while in custody, it denied the
    motion as to evidence of (1) statements that he made at the time
    of his arrest, and (2) two items (.38 caliber bullets and a plastic
    pistol) that were seized from his vehicle when he was arrested.
    López-Soto had moved to suppress on the theory that the government
    lacked probable cause to arrest him and search his vehicle.              López-
    Soto argues that the district court erred in denying his motion to
    suppress and his request for a suppression hearing.                 We disagree.
    López-Soto has not established error in the district
    court's suppression rulings.             "When reviewing a district court's
    disposition of a motion to suppress, we accept the court's findings
    of   fact    unless   they      are    clearly    erroneous   and   subject   its
    conclusions of law . . . to de novo review."                  United States v.
    Brown, 
    500 F.3d 48
    , 53 (1st Cir. 2007).              López-Soto contends that
    the district court erred in denying his motion to suppress "just
    and only because" he did not file an affidavit under penalty of
    perjury     in   support   of    his    motion.      This   misunderstands    the
    district court's ruling.              The district court properly concluded
    that probable cause was established by the combination of (1) an
    informant's tip as to López-Soto's location; and (2) video footage
    of a robbery that was used to identify López-Soto as a perpetrator.
    Though the district court indicated that its denial was without
    - 22 -
    prejudice to a renewed motion to suppress based on an affidavit by
    López-Soto      (or   another),     the       district   court    did    not    deny
    suppression due to the lack of such an affidavit.
    Nor did the district court err in denying López-Soto's
    request   for    a    suppression    hearing.         López-Soto's       motion   to
    suppress was premised entirely on undisputed facts, and his one-
    line request for a hearing did not explain the purpose that a
    hearing would serve.        It was not an abuse of discretion for the
    district court to conclude that, without a showing in the form of
    a sworn statement that would create a material factual dispute, a
    hearing on the motion to suppress was unnecessary.
    2
    López-Soto    argues    that      the   district    court    erred   in
    denying his motion for acquittal for two of the firearm counts of
    which he was convicted: brandishing a firearm during a Hobbs Act
    robbery under 18 U.S.C. §§ 924(c)(1)(A)(ii) and 2 (Case No. 14-
    cr-415, Count Two), and possession of a firearm by a convicted
    felon under 18 U.S.C. §§ 922(g)(1) and 2 (Case No. 14-cr-415, Count
    Three).   López-Soto was convicted under the theory that he aided
    and abetted García in the commission of these offenses.                        To be
    convicted as an accomplice to a section 924(c)(1)(A)(ii) offense,
    the government had the burden to show beyond a reasonable doubt
    that López-Soto knew "to a practical certainty" that García would
    brandish a gun.        See United States v. Spinney, 
    65 F.3d 231
    , 234
    - 23 -
    (1st Cir. 1995) (quoting United States v. Torres-Maldonado, 
    14 F.3d 95
    , 103 (1st Cir. 1994)).     To be convicted as an accomplice
    to the section 924(g) offense, the government had the burden to
    show that López-Soto knew that García possessed a firearm.          See
    United States v. Ford, 
    821 F.3d 63
    , 74 (1st Cir. 2016).          López-
    Soto asserts the government failed to meet this burden.
    "We review [a district court's decision to deny a motion
    for acquittal] de novo, but our review . . . is 'quite limited; we
    must affirm unless the evidence, viewed in the light most favorable
    to the government, could not have persuaded any trier of fact of
    the defendant’s guilt beyond a reasonable doubt.'"        United States
    v. Hernandez, 
    218 F.3d 58
    , 64 (1st Cir. 2000) (quoting United
    States v. Paradis, 
    802 F.2d 553
    , 559 (1st Cir. 1986)).
    There   was   ample   evidence   to   support   the   verdict.
    Cooperating co-defendant García testified that, on June 3, 2014,
    he and López-Soto robbed an AT&T store in Lares, Puerto Rico, and
    that in the robbery García had brandished a .38 caliber revolver.
    The evidence supported a finding that López-Soto knew García
    possessed and would brandish the revolver.      García testified that:
    (1) López-Soto had sold the revolver to him, (2) García had visibly
    handled and inspected the weapon in the car -- while López-Soto
    was in the other front seat -- before the robbery, (3) "we always
    carried it [i.e., the gun] with us" during robberies, and (4)
    López-Soto "was aware that [García's] modus operandi was to always
    - 24 -
    show the firearm during the robberies."            Based on this testimony,
    "a rational jury could have found that the government proved the
    [knowledge] elements of the crime[s] beyond a reasonable doubt."
    See United States v. Appolon, 
    715 F.3d 362
    , 367 (1st Cir. 2013)
    (quoting United States v. Mardirosian, 
    602 F.3d 1
    , 7 (1st Cir.
    2010)).
    3
    López-Soto   argues    that    the   district    court   erred   in
    denying his motion for acquittal as to all counts because none of
    the victims identified López-Soto at trial.           López-Soto's argument
    lacks merit.      This court has never required that a victim identify
    the defendant, but has instead "repeatedly . . . held that 'the
    uncorroborated testimony of a cooperating accomplice may sustain
    a   conviction     so   long   as   that     testimony   is     not   facially
    incredible.'"      United States v. Cortés-Caban, 
    691 F.3d 1
    , 14 (1st
    Cir. 2012) (quoting United States v. Torres–Galindo, 
    206 F.3d 136
    ,
    140 (1st Cir. 2000)).          Here, not one but two cooperating co-
    defendants -- García and Ruiz -- testified as to López-Soto's
    participation in the robbery scheme of which he was accused.
    Documentary evidence, physical evidence, and the testimony of many
    victims    and   government    agents   corroborated     García   and   Ruiz's
    testimony.       The evidence is more than sufficient to sustain the
    verdict.
    - 25 -
    E.
    López-Soto   challenges       various   other   rulings   of     the
    district court.
    1
    López-Soto   argues   that     the   district    court   erred    in
    consolidating the two cases for which he was being prosecuted.
    The court reviews joinder decisions de novo.              United States v.
    Ponzo, 
    853 F.3d 558
    , 568 (1st Cir. 2017)            López-Soto does not
    appear to contest the propriety of joinder under Federal Rule of
    Criminal Procedure 13.   Nor has López-Soto demonstrated prejudice
    sufficient to foreclose joinder.        See Fed. R. Crim. P. 14.     López-
    Soto has not shown error in the consolidation of these cases.
    2
    López-Soto contends that the district court's denial of
    his request for a continuance of the start of the trial was an
    abuse of discretion and violated his Sixth Amendment rights.               The
    court "review[s] a denial of a motion for a continuance for abuse
    of discretion."   United States v. Arias, 
    848 F.3d 504
    , 514 (1st
    Cir. 2017).   "If the denial of a continuance effectively deprives
    a pro se defendant of the ability to represent himself, it may
    constitute both an abuse of discretion and a Sixth Amendment
    violation."   Barham v. Powell, 
    895 F.2d 19
    , 22 (1st Cir. 1990).
    Because López-Soto raises this argument for the first time on
    - 26 -
    appeal, we review the district court for plain error.                    See United
    States v. González-Barbosa, 
    920 F.3d 125
    , 128 (1st Cir. 2019).
    At a hearing three days before trial, the district court
    gave final approval to López-Soto's request to represent himself
    at trial.    López-Soto then moved to continue his trial, contending
    primarily   that   he    did   not   have    enough     time    to    "confer    with
    witnesses" that he intended to call.             The district court denied
    the continuance.     As the district court noted, López-Soto had been
    requesting to represent himself for over a year and had been filing
    pro se motions for two years.          The district court concluded López-
    Soto would have adequate time to prepare his witnesses.
    On appeal, López-Soto asserts that he did not have
    sufficient time to review video recordings of the robberies of
    which he was accused.       But, at the pre-trial hearing, the district
    court    ordered   the   government     to    provide    López-Soto       with    the
    recordings; López-Soto suggested at trial that he had seen them;
    and López-Soto did not thereafter raise the issue at the district
    court.    In failing to articulate with particularity how additional
    time would have improved his effectiveness at trial, López-Soto
    has not met his "heavy burden" to "show that the judge's decision
    caused   specific,      'substantial    prejudice.'"           United    States   v.
    Robinson, 
    753 F.3d 31
    , 41 (1st Cir. 2014) (quoting United States
    v. Maldonado, 
    708 F.3d 38
    , 42 (1st Cir. 2013)).                      López-Soto has
    - 27 -
    not shown that the district court abused its broad discretion in
    declining to continue the trial.
    3
    López-Soto challenges the district court's denial of
    many of his pro se pretrial motions.       So long as López-Soto was
    represented by counsel, he had no right to file his own motions.
    López-Soto "has no right to hybrid representation" by himself and
    counsel simultaneously.      See United States v. Nivica, 
    887 F.2d 1110
    , 1121 (1st Cir. 1989).         "That is not to say that hybrid
    representation   is   foreclosed;    rather,   it   is   to   be   employed
    sparingly and, as a rule, is available only in the district court's
    discretion."
    Id. We review
    the district court's decision to not
    allow hybrid representation for abuse of discretion.
    Id. Here, the
    court noted that López-Soto's counsel were "excellent" and had
    "vast experience here in court precisely in this type of case,"
    whereas López-Soto had "no experience in any legal analysis."          The
    district court did not abuse its discretion in declining to
    consider his pro se motions while he was represented by counsel.
    In any event, López-Soto presents no developed argument
    as to what motions were erroneously denied, merely citing docket
    numbers of the motions and the district court’s corresponding
    orders.   These motions generally requested the court to compel the
    government to produce directly to López-Soto evidence it intended
    to use at trial.      The court denied many of these pro se motions
    - 28 -
    because López-Soto was, at the time, being represented by two
    attorneys.        The court ordered López-Soto "to provide his counsel
    with a copy of any motion he wishes to file for counsel to perfect
    the motion and duly file it."
    López-Soto has not shown any error in the court's denial
    of    his   pro     se    motions.         López-Soto       has     not   specifically
    articulated       why     he    needed    the      evidence    directly      from    the
    government.        He states that the motions were "important for the
    preparation       of     the   defendant's      defense"      and    notes    that   the
    government did not respond to many of these motions.                         But López-
    Soto does not explain, for example, why he could not obtain
    government evidence from his counsel, and why instead he needed a
    court order that the government produce it to him directly.                         There
    was no abuse of discretion by the district court in rejecting
    López-Soto’s motions.

    López-Soto also contends that the district court erred
    in "allowing the US government to file a second response to [López-
    Soto's] motion" for acquittal.             The government's original response
    to López-Soto's motion for acquittal did not include citations to
    the   record.          The     district    court,     sua     sponte,     ordered    the
    government to refile its response -- with citations to the record
    -- within four business days.              The district court's ruling was not
    an abuse of discretion.

    F.
    Finally, López-Soto argues that his sentence of 744
    months     of   imprisonment     is     substantively       unreasonable.      He
    acknowledges     that    "the   statutory       and    guidelines   calculations
    appear to be correctly applied and accurate," but primarily argues
    that "in the face of his codefendants' more extensive charged
    criminal acts," the substantially higher sentence that he received
    is unreasonable.        López-Soto did not raise the issue of disparity
    between his sentence and that of his co-defendants before the
    district court.     We therefore review the district court's sentence
    only for plain error.       See 
    Gonzalez-Bárbosa, 920 F.3d at 128
    .
    All three of López-Soto's co-defendants pled guilty to:
    (1) a RICO violation under 18 U.S.C. §§ 1962(d) and 1963(a); and
    (2) carrying a firearm during and in relation to a crime of
    violence under 18 U.S.C. §§ 924(c)(1)(A).                    Co-defendant Jesús
    Ramírez-Cotto was sentenced to 171 months of imprisonment.                     Co-
    defendant Ruiz's sentence was sealed, but his plea appears to have
    recommended a sentence between 205 and 235 months.                  Co-defendant
    García's    sentence      was   also    sealed,       but   his   plea   agreement
    recommended a sentence between 262 and 327 months.
    Title 18, section 3553(a) provides factors that a court,
    "in determining the particular sentence to be imposed, shall
    consider."      Section 3553(a)(6) notes "the need [in sentencing] to
    - 30 -
    avoid      unwarranted      sentence     disparities      among     defendants     with
    similar records who have been found guilty of similar conduct."
    Here, focusing on the disparities of the defendants, and
    even assuming that the sentences of Ruiz and García were within
    the range proposed, López-Soto's disparity argument fails.                      "Since
    the District Judge correctly calculated and carefully reviewed the
    Guidelines      range,      he   necessarily      gave   significant      weight    and
    consideration to the need to avoid unwarranted disparities."                       Gall
    v.    United    States,     
    552 U.S. 38
    ,     54   (2007)      (emphasis   added).
    "Although this section is primarily aimed at national disparities,
    rather than those between co-defendants, a district court may
    consider differences and similarities between co-defendants at
    sentencing."       United States v. Marceau, 
    554 F.3d 24
    , 33 (1st Cir.
    2009) (citation omitted).
    There is no showing of an unwarranted disparity.                 López-
    Soto's co-defendants were not "found guilty of similar conduct."
    See   18    U.S.C.    § 3553(a)(6).       Though       some   of    López-Soto's    co-
    defendants were charged with more crimes than López-Soto, all three
    co-defendants        were    convicted    of    fewer    crimes.        Notably,    for
    example, López-Soto was convicted of three Hobbs Act robberies,
    whereas none of his co-defendants was convicted of any.
    So too, all co-defendants to whom López-Soto compares
    himself pled guilty (López-Soto did not), and two of the three
    cooperated with law enforcement (López-Soto did not).                     This court
    - 31 -
    has   recognized    "the   permissible     distinction"    for   sentencing
    purposes "between co-defendants who go to trial and those who plead
    guilty" and "between those who cooperate and those who do not."
    United States v. Reyes-Santiago, 
    804 F.3d 453
    , 467 (1st Cir. 2015).
    In light of these differences between his co-defendants
    and himself, López-Soto cannot show "clear[ly] or obvious[ly]"
    that the district court abused its discretion in imposing its
    sentence.     See    
    González-Barbosa, 920 F.3d at 128
      (“Courts
    frequently reject disparity claims . . . when appealing defendants
    ignore material differences between their own circumstances and
    those of their co-defendants.”).
    III.
    We conclude that the district court erred in providing
    its medical care instruction to the jury, but find this error to
    be harmless in light of the overwhelming evidence of López-Soto's
    guilt.   For López-Soto's remaining challenges, we find that he has
    not shown that the district court plainly erred or abused its
    discretion.
    As the government notes in its Informative Motion, the
    district court -- in sentencing López-Soto to 360 months for Count
    One of Case No. 14-cr-415 and Counts One, Fourteen, and Fifteen of
    Case No. 14-cr-637 -- exceeded the statutory maximum of 240 months
    for these offenses.        See 18 U.S.C. §§ 1951(a) and 1963(a).           We
    - 32 -
    vacate the district court’s sentence in this respect and remand
    for the district court to enter a sentence of 240 months for these
    counts to be served concurrently with each other.      See United
    States v. Almonte-Nuñez, 
    771 F.3d 84
    , 92 (1st Cir. 2014)
    Affirmed-in-part, vacated-in-part, and remanded.
