    Judge Boudin heard oral argument in this matter and
    participated in the semble, but he did not participate in the
    issuance of the panel's opinion. The remaining two panelists issue
    this opinion pursuant to 
    28 U.S.C. § 46
    (d).
    THOMPSON, Circuit Judge.         Based on tips from three
    confidential informants -- we refer to them collectively as CIs,
    and individually as CI-1, CI-2, and CI-3 -- federal agents in Maine
    suspected that James Mills had been smuggling oxycodone into the
    United States from Canada for some time, occasionally hiding the
    pills in condoms inserted into his rectum.           Armed with this and
    other information, agents nabbed a suspiciously-acting Mills at the
    border on a return trip from Canada.      One thing led to another and
    agents ended up handcuffing him to a hospital bed to monitor his
    impending bowel movement.        Eventually he passed a condom that
    contained 104 80-milligram and 5 40-milligram oxycodone pills.
    Mills   later   pled   guilty   to   one   count   of   importing
    oxycodone.   See 
    21 U.S.C. § 952
    (a).      At sentencing, the district
    court assigned him a drug quantity equivalent to 2,637 80-milligram
    oxycodone pills based in part on uncharged conduct described by the
    CIs, see U.S.S.G. § 1B1.3(a)(2), after having earlier denied his
    motion to force the government to disclose the CIs' names. Relying
    on this increased drug quantity rather than simply the 109 pills
    found in the condom, the court sentenced Mills to 108 months in
    prison, a sentence increase of seven years, Mills complains.
    Mills now appeals, arguing that the court erred in
    denying his disclosure motion and in calculating the drug quantity.
    Having carefully considered his claims, we find no error and
    affirm.

    BACKGROUND
    A. The Events Surrounding Mills' Arrest
    At approximately 6:45 p.m. on September 11, 2009, Mills
    entered the Lubec, Maine Port of Entry to the U.S. from Campobello
    Island,   Canada.   Tipped     off   by    a    confidential    informant,     law
    enforcement officers were awaiting Mills' arrival at the border.
    Upon his entry, Mills was directed for secondary inspection where
    Customs and Border Protection (CBP) and Immigration and Customs
    Enforcement (ICE) officers noticed he was acting nervous, avoiding
    eye contact, and breathing erratically.                The officers asked Mills
    where he had been earlier; he responded he was on Campobello Island
    all day, but later changed his story after store receipts from St.
    John, New Brunswick were found in his vehicle.                 When the agents
    questioned him, Mills denied carrying pills, and a pat down and
    partial body search revealed none.             After he refused to consent to
    an x-ray of his body, the agents took Mills to Calais Regional
    Hospital for a monitored bowel movement.               Mills was handcuffed to
    a hospital bed and told he would stay handcuffed until he had to
    use the bathroom.       Meanwhile, ICE officers sought a warrant and
    court order to conduct an x-ray and body cavity search.
    The following morning at approximately 8:06 a.m., Mills
    agreed to an x-ray and the results indicated he had a foreign
    object in his alimentary canal.           The ICE officers told Mills about
    the   x-ray   results    and    he   agreed       to    pass   the   object;   at
    -3-
    approximately 8:59 a.m. Mills passed a condom that contained 104
    80-milligram    pills   and   5   40-milligram   pills.   CBP   officers
    processed the package as evidence and found the pills in Mills'
    possession totaled 8.5 grams of Canadian-manufactured OxyContin, a
    brand of the prescription drug oxycodone.1         A federal grand jury
    returned a one-count indictment charging Mills with knowingly and
    intentionally importing oxycodone into the U.S. on September 11,
    2009, in violation of 
    21 U.S.C. § 952
    (a), and on January 7, 2010,
    he plead guilty as charged without a plea agreement.
    B. The Recommended Sentence and Accompanying Evidence
    At the sentencing stage, the only real issue concerned
    the proper quantity of oxycodone for which Mills was to be held
    responsible.     Consequently, we relate only what is necessary to
    place that issue into proper perspective.
    Using the then-current edition of the federal sentencing
    guidelines, the probation office prepared a pre-sentence report
    (PSR) that attributed to Mills not only the 8.5 grams of oxycodone
    he possessed when arrested but also an additional 295.4 grams of
    oxycodone under the guidelines' relevant conduct provision.         See
    United States v. Marquez, 
    699 F.3d 556
    , 558 (1st Cir. 2012)
    (explaining that "a defendant is responsible not only for the
    wrongdoing to which he pled or of which he was convicted, but also
    1
    The pills were marked with "CDN," indicating the oxycodone
    was of Canadian manufacture.
    -4-
    for 'all acts and omissions . . . that were part of the same course
    of conduct or common scheme or plan as the offense of conviction'")
    (alteration in original) (quoting U.S.S.G. § 1B1.3(a)(2)). Here is
    how probation reached that number:
    Documents offered by the government showed that Mills
    crossed the border from Canada into Maine 231 times between January
    and September 2009. They also showed that Mills converted $369,203
    of U.S. currency into Canadian currency between May 2008 and
    September 2009.      For each transaction Mills had to disclose where
    the cash had come from.      And he claimed that the funds were payment
    for his work as a sea urchin diver and carpenter, for example.          But
    the   amounts   he     exchanged    were    significantly    greater    and
    inconsistent    with   the   "legitimate"    earnings   he   reported    to
    probation.   Also, Mills had given the names of two people who had
    supposedly provided him with money on the up and up, and both of
    them denied ever doing so, probation noted. Critically, once Mills
    learned about the currency exchange records, he changed his story,
    saying in a recorded jailhouse conversation with his girlfriend
    that he had been exchanging the cash for someone else and getting
    free drugs for his trouble.        Critically too, one CI reported that
    Mills routinely smuggled 100 pills at a time into the U.S. in his
    rectum, and another said pretty much the thing.
    Using the street value of oxycodone, $100 a pill, and the
    $369,203 in currency exchanges, probation then calculated Mills had
    -5-
    smuggled at least 3,692 80-milligram oxycodone pills or 295.4 grams
    of actual oxycodone prior to his arrest.                     See id. at 561 (noting
    that    "[e]xtrapolation      is     a    common     and       permissible     way     of
    attributing drugs to a defendant").                  The sentencing guidelines
    provide a formula for converting drugs into equivalent units of
    marijuana    for    sentencing       purposes:       1       gram    of   oxycodone    is
    equivalent to 6,700 grams of marijuana.                  See U.S.S.G. § 2D1.1 cmt.
    n.10(E) (since recodified as cmt. n.8(D)).                          So 295.4 grams of
    oxycodone amounted to 1,979 kilograms of marijuana equivalent,
    which, when combined with the 8.5 grams of oxycodone Mills smuggled
    on    September    11,   brought     his    marijuana          equivalent     to   2,036
    kilograms. The base offense level for at least 1,000 kilograms but
    less than 3,000 kilograms of marijuana is 32.                             See U.S.S.G.
    §    2D1.1(c)(4).        Probation       suggested       a    3-level     decrease    for
    acceptance of responsibility, see U.S.S.G. § 3E1.1, and another 2-
    level decrease if he satisfied the test for "safety valve" relief,
    see U.S.S.G. § 5C1.2 -- to be eligible a defendant, among other
    things, must by the time of sentencing truthfully provide "the
    [g]overnment all information and evidence [he] has concerning the
    offense or offenses that were part of the same course of conduct,"
    id. § 5C1.2(a)(5).        That would give him a total offense level of
    27, which, when paired with his criminal history category of I,
    would yield a sentencing range of 70 to 87 months in prison.
    -6-
    The    government   also    asked   the    court   to    hold   Mills
    responsible for 295.4 grams of oxycodone under the relevant conduct
    rubric,   using   the   same   math   as    probation.     To    avoid     double
    counting, the government's drug-quantity estimate did not include
    the oxycodone seized from him on September 11.                  The government
    presented six exhibits to back up its argument.               Exhibit 1 was a
    summary spreadsheet of records obtained from the Royal Canadian
    Mounted Police (RCMP) documenting Mills' 108 currency exchanges
    involving a total of $369,203, which he made during the 16 months
    before his arrest. The last documented transaction in the currency
    exchange records was only two days before his capture, and he made
    other cash exchanges on September 2, 4, and 7.                Exhibit 6 was a
    compilation of records that supported Exhibit 1.
    Exhibit 2 was the ICE report of CI-1, who reported seeing
    Mills with between 50 and 100 oxycodone tablets at least once a
    week between spring 2006 and spring 2007.            CI-1 stated Mills would
    go to St. Andrews, New Brunswick, Canada to purchase the pills and
    then smuggle them into the U.S. for sale (other evidence showed) in
    Washington County, Maine.
    Exhibit 3 was a report from the RCMP summarizing the
    statements of CI-2. CI-2 said Mills would first collect money from
    prospective U.S. buyers, convert that money from U.S. currency to
    Canadian currency, acquire pills from his supplier, and then return
    to Maine by crossing at the Lubec Port of Entry.                   According to
    -7-
    CI-2, Mills would smuggle about 100 pills at a time into the U.S.
    internally, via his rectum.
    Exhibit 4 was an ICE report regarding an investigation
    that began in September 2008, after an undercover agent of the
    Maine Drug Enforcement Agency purchased OxyContin from CI-3. CI-3,
    an admitted oxycodone addict, named Mills as his or her supplier.
    According to CI-3, Mills would get money from his clients prior to
    purchasing the pills in Canada, and would then smuggle the pills by
    taping them to his groin area or having his girlfriend smuggle them
    internally.    CI-3 further stated Mills would bring the pills into
    the U.S. by making two trips each week with 100 to 200 pills per
    trip.   Exhibit 5 was the proffer report of CI-3, which reiterated
    many of the statements CI-3 made in Exhibit 4.                    In this proffer,
    CI-3 noted the pills Mills smuggled were Canadian brand OxyContin
    because they were labeled "CDN."                   CI-3 also said 80-milligram
    oxycodone pills sold for $80 to $100 a piece.
    Wrapping up, the government stressed how consistent the
    CIs' accounts were with each other on the modus operandi of Mills'
    criminal     endeavors         and    how    the    currency    exchange        records
    corroborated all this by showing his access to a large pool of
    money to     fund   his    drug-buying sprees.            Also,      the   government
    emphasized    how     Mills'         employment     records    showed      he   had    no
    legitimate    means       of    obtaining     the    amounts    of    cash      he    was
    exchanging, noting in particular the statements of two persons whom
    -8-
    Mills said had given him money lawfully, who denied any such
    transaction.
    Mills' sentencing memorandum argued the appropriate drug
    quantity was the 8.5 grams of oxycodone he was caught with.                And he
    blasted the government for relying on the untested assertions of
    CIs in coming up with its proposed drug quantity calculation.
    C. The Identities of the CIs
    At a pre-sentencing conference in July 2010, Mills'
    lawyer contested the use of the CIs' statements and the financial
    records   as   evidence    of   drug    smuggling.    Specifically,    counsel
    explained his concern about the veracity of the CIs, since the
    government was offering their statements in support of a drug
    quantity that increased the amount attributable to him almost 50-
    fold.   To bolster his argument, counsel cited a recorded jailhouse
    telephone conversation between Mills and his girlfriend in which
    they discussed how the currency exchanges were part of a money
    laundering scheme, and not, as the CIs' statements suggested, part
    of his drug trafficking.          Counsel maintained this conversation
    called into question the reliability of the CIs' statements,
    particularly to determine the drug quantity attributable to Mills.
    Expressing     concern    about   the     court's    reliance   on   the    CIs'
    unrebutted claims, counsel requested disclosure of their identities
    in order to speak with them and potentially bring them into court.
    -9-
    The court stated its surprise that Mills could not
    determine the CIs' identities based on what had already been
    revealed and the presumably limited number of people involved in
    dealing OxyContin in Washington County, Maine.                     In response to
    Mills' argument for disclosure, the government noted two troubling
    incidents. First, a woman attempting to enter the U.S. from Canada
    had a letter from Mills on her that included pages from his PSR.
    Mills' letter stated the government was trying to prove additional
    drug quantity against him but would have trouble doing so without
    someone testifying against him. Second, after the government filed
    its sentencing memo, one of the CIs contacted ICE to report that
    copies of the redacted CI reports filed with the court had been
    published    on    the    Facebook      page   of    Mills   and    his    longtime
    girlfriend, Jennifer Smart.          The government noted that the lawyer
    for another of the CIs made the same complaint and that the CIs
    were afraid.        Arguing they had an obligation to protect the
    informants and their identities, the government asserted that the
    potential for Mills to post the CIs' identities on Facebook raised
    significant safety concerns.
    Even though the government later handed over impeaching
    material    on    the    CIs,   Mills    moved      for   disclosure      of   their
    identities.       Citing to Brady v. Maryland, 
    373 U.S. 83
     (1963), he
    asserted he was faced with CIs making statements against him, which
    if adopted by the court could be "material to his punishment."
    -10-
    Brady    held,   "the   suppression    by    the   prosecution   of    evidence
    favorable to an accused upon request violates due process where the
    evidence is material either to guilt or to punishment." 
    Id. at 87
    .
    Mills argued the "identity of these informants, then is itself
    evidence 'favorable to the accused' where it will allow [him] to
    challenge and to test these assertions," which he insisted were
    false.
    In the conference of counsel the next day, Mills' lawyer
    explained disclosure was necessary for the defense to determine the
    accuracy of the drug quantity the government attributed to him. He
    argued the large amounts of money represented in the currency
    exchange records were attributable to his money laundering for
    someone in Canada, so to the extent the court was relying on the
    CIs' statements to determine the source of that money, the veracity
    of the statements would be important for the court.                   The court
    again noted its disbelief that Mills could not determine the
    identities of the CIs himself, based on the descriptions of their
    statements, and Mills' lawyer countered his client would only know
    who the CIs were if the statements they made were true.                     The
    government again discussed how the CIs' statements were consistent
    with one another and with the currency exchange records and how
    Mills' posting of CI information on Facebook put them at great
    risk.    And the court warned Mills he was running the risk of not
    getting any adjustment for acceptance of responsibility as it
    -11-
    seemed what he truly wanted was the CIs' identities in order to
    declare them snitches to his compatriots, and have retribution
    taken against them.
    Ultimately, the court denied the motion. The court found
    the CIs' statements were corroborated by other reliable evidence.
    Comparing Mills' need for access to the CIs with the physical
    danger   to    them,   and   with   the   danger   of   compromising   other
    government investigations, as required under United States v.
    Tzannos, 
    460 F.3d 128
    , 139 (1st Cir. 2006), the court stressed
    Mills had given "no concrete reason to override the [g]overnment's
    interest in keeping [their] identities" under wraps.            And as for
    Brady, the court found that case distinguishable from Mills': Mills
    sought disclosure at sentencing, not during trial, and Mills "made
    no showing that disclosure of the CIs' identities would be either
    material or favorable."
    At the next conference of counsel, Mills' lawyer said his
    client would not seek safety valve relief.          He also said Mills had
    hired a private investigator to determine the CIs' identities.
    And, he added, he intended to have the investigator testify at the
    upcoming sentencing hearing so that the court could hear what the
    investigator learned after talking with some suspected CIs.              The
    court said that was okay and then ticked off the evidence that it
    already had:     (a) Mills' admission that September 11, 2009 was not
    his first time smuggling OxyContin into the U.S.; (b) documents
    -12-
    showing "enormous amounts of cash, in excess of $300,000," that
    Mills had converted from U.S. to Canadian dollars; and (c) evidence
    showing that Mills' legitimate sources of income "don't begin to
    generate the kind of money" he had exchanged.          Adding everything
    together, the court suggested it mattered not what the CIs might
    say.    "[T]he fact that confidential informants say what I think I
    can infer anyway," the court stressed, "is icing on the cake."
    D. The Sentencing Hearing
    Mills'   sentencing     hearing   went   forward       with   the
    identities of the CIs still secret.       Conceding September 11, 2009
    was not his client's first time smuggling oxycodone into the U.S.,
    Mills' lawyer focused on the currency exchange records and argued
    the bulk of the money had come from an illegal source, but not from
    Mills' drug smuggling.        Mills' private investigator explained in
    testimony at the hearing how Mills had hooked up with a Canadian
    marijuana dealer who sometimes got paid in U.S. currency and how
    the dealer would pay Mills in Oxycontin if he (Mills) converted
    that cash into Canadian currency -- at least that is what Mills'
    investigator claimed Mills had told him.         That story squared with
    the    recorded   jailhouse   telephone   call   between   Mills    and   his
    girlfriend in which they talked about how the currency exchanges
    were part of a money laundering venture, Mills' investigator added.
    And he also testified that he questioned possible CIs, all of whom
    denied providing any information to law enforcement about Mills'
    -13-
    drug trafficking, and that he was unable to find anyone who
    admitted providing information about Mills to the authorities.
    Cross-examined by the government, Mills' investigator
    noted that when he asked Mills to reveal the marijuana dealer's
    name, Mills said, "I'd rather not disclose that."            Ultimately, the
    government       argued    nothing   in   the   investigator's    testimony
    necessarily undermined the evidence as to drug quantity.              "[T]here
    is   no   weed   dealer,"    the   government   insisted.     "This    is   all
    OxyContin money."         So the government urged the court to rely on
    Mills' admission concerning his prior smuggling and the CIs'
    statements describing his drug dealing history.             Recognizing some
    differences in the CIs' stories, the government explained it was
    not asking the court to adopt the specific drug quantities cited in
    the CIs' statements, but instead to use the border patrol and
    currency exchange records to determine the total drug quantity.
    After considering the evidence and hearing counsel's
    arguments, the court made a number of critical findings.                    For
    openers, the court found that Mills had crossed the border from
    Canada into Maine 231 times in the 8 months before his arrest.
    Also, the court found that the CIs' accounts fit together nicely on
    a number of fronts:        e.g., that Mills had been smuggling OxyContin
    for a long time; that he would first get money from U.S. customers
    and then head to Canada to buy pills to smuggle back to Maine,
    often hiding the pills in his rectum; and that he would sneak in
    -14-
    about 100 pills or so each time.     "All of that," the court found,
    was "remarkably consistent with what we know happened on September
    11, 2009."    On top of that, the court found that the frequency and
    amount of Mills' currency exchanges suggest the $369,203 was tied
    to his drug dealings.
    Taking up Mills' claim that the currency exchange report
    reflected other sources of money besides his oxycodone trafficking,
    the court rejected his uncorroborated explanations.         "I do not
    believe the story about the major marijuana dealer using [Mills] to
    convert currency," the court said.        "I just don't believe it,"
    particularly since Mills had refused to give up the dealer's name,
    leaving no way to verify his claim.     "We don't know the CIs' names,
    the court noted, but "we know what [they] have said" and so "we can
    compare them."    As for Mills' theory that some of the currency was
    payment for his work as a sea urchin diver and carpenter, the court
    found no proof of that, since Mills had failed to file income taxes
    with the federal government and his alleged employers denied paying
    him any cash.
    Applying the correct version of the guidelines (the
    parties do not say otherwise), the court then took the $369,203 and
    Mills' preferred $140 per-pill value and arrived at a drug quantity
    of 1,374.4 kilograms of marijuana equivalent. The court's math was
    off just a bit, though.     $369,203 divided by $140 equals 2,637.16
    pills, which, at 80-milligrams each, produces 210.97 grams of

    oxycodone.   Multiplying 210.97 grams by 6,700 yields a marijuana
    equivalent of 1,413.52 kilograms, not 1,374.4 kilograms.                    But that
    mistake makes no difference to Mills, given that both numbers fall
    within the 1,000 to 3,000 kilograms range, which put him in base
    offense level 32 regardless.            See U.S.S.G. § 2D1.1(c)(4).           Next,
    the court granted Mills a 3-level acceptance of responsibility
    reduction.   With no safety valve adjustment, Mills' total offense
    level was 29.      That offense level, combined with his criminal
    history category of I, resulted in a sentencing range of 87 to 108
    months. And after working its way through the factors listed in 
    18 U.S.C. § 3553
    (a), the court imposed a top-of-the-range prison
    sentence of 108 months.
    DISCUSSION
    Training       his   sights    on     the    CIs,     Mills   attacks   his
    sentence on two fronts.        First, he faults the court for denying his
    motion for disclosure, arguing that he needed to know the CIs'
    identities   so   that    he   could     defend       against    the    government's
    sentencing   arguments.         Second,        he   criticizes     the    court   for
    attributing to him a drug quantity beyond the amount involved in
    the charged offense, contending that if the court had required
    disclosure of the CIs' names, he could have shown that what they
    had said was too unreliable for calculating relevant conduct under
    the sentencing guidelines.        Neither persuades.

    A. Disclosure of the CIS' Identities
    Police    use   confidential   informants   all   the   time,
    particularly in the murky world of drug dealings.            See United
    States v. Perez, 
    299 F.3d 1
    , 2-3 (1st Cir. 2002).      But snitching is
    dangerous work, and informants literally put their lives on the
    line by doing what they do.     See 
    id. at 3
    .   With so much at stake,
    confidentiality is key.     See 
    id.
       And that is where the "tattler's
    privilege" comes in -- that is, the government's privilege to keep
    secret the names of persons who give law enforcement information
    about crimes.    United States v. Robinson, 
    144 F.3d 104
    , 106 (1st
    Cir. 1998) (discussing Roviaro v. United States, 
    353 U.S. 53
    (1957)).
    But important as that privilege is, it is not absolute;
    where the disclosure of an informant's identity is "relevant and
    helpful to the defense of an accused, or is essential to a fair
    determination of a cause, the privilege must give way."        Roviaro,
    
    353 U.S. at 60-61
    .    One should not go overboard when reading that
    quote, however.     The high Court could not have meant "that the
    privilege covers only irrelevant and unhelpful" or nonessential
    "evidence."     See United States v. Gaston, 
    357 F.3d 77
    , 84 (D.C.
    Cir. 2004) (explaining why that must be so).
    A disclosure inquiry is case-specific -- there is no
    "mechanical solution[]."     Perez, 
    299 F.3d at 4
    .     Starting with a
    presumption in favor of confidentiality, see Robinson, 144 F.3d at
    -17-
    106, a trial court must "balanc[e] the accused's right to prepare
    and present his defense against the public interest in acquiring
    needed information and the informant's stake in confidentiality,"
    Perez, 
    299 F.3d at 4
    .   Other factors that typically go into the mix
    include "the nature of the crime charged, the contours of the
    defenses asserted, the available means of proving the charges and
    defenses, and the significance of the informant's role." Robinson,
    
    144 F.3d at 106
    .
    The burden is squarely on the defendant to show that
    disclosure is essential for an adequate defense -- and it is a
    "heavy" one; it is not met by speculating about how useful an
    informant's testimony might be, for example.      United States v.
    Cartagena, 
    593 F.3d 104
    , 113 (1st Cir. 2010) (quoting United States
    v. Lewis, 
    40 F.3d 1325
    , 1335 (1st Cir. 1994)).     But heavy is not
    code for impossible.    See Robinson, 
    144 F.3d at 106
    .   Suppose the
    informant is the only person other than the defendant who has
    firsthand knowledge of the acts underlying the crime charged.    Or
    suppose the informant is the only one able to amplify or contradict
    the testimony of a government witness.        Either situation may
    justify disclosure, we have said.      
    Id.
     (relying on Roviaro).
    Simplifying things somewhat, Mills has not shown how his case fits
    one of these scenarios.   Or any other equally compelling scenario,
    as we shall see after applying abuse of discretion review.   See 
    id.
    (stressing how that standard "is quite deferential: the district
    -18-
    court's resolution of a disclosure request should be upheld as long
    as it comports with some reasonable rendition of the record").
    A moment ago we noted that Mills says that knowing the
    CIs' names was necessary for the court's calculation of his drug
    quantity.   The problem for him is that he does not tell us why this
    is so.   Obviously, a defendant must spell out how an informer's
    testimony would help whatever defense theory he pins his hopes on.
    See United States v. Martinez, 
    922 F.2d 914
    , 921 (1st Cir. 1991).
    Mills' story seemed to change like the weather.   But the one he ran
    with at sentencing suggested that the cash reflected in the all-
    important currency exchange records came either from a money
    laundering conspiracy involving a major-league Canadian marijuana
    dealer or from his work as a sea urchin diver and carpenter -- or
    perhaps both.    Yet, devastating to his position, he whispers not
    even a hint that the CIs could have shed any light on this late-
    emerging defense.     See 
    id.
     (putting the onus on defendants "to
    provide at least some explanation of how the informant's testimony
    would have supported their alleged defenses").
    The "heart" of the court's drug quantity analysis is the
    CIs' statements, Mills protests a little later in his brief.    Not
    so.   Even a quick review of the record shows that what principally
    drove the court's decision were (a) the 108 currency exchanges
    totaling $369,203 that Mills had made during the 16-month stretch
    -19-
    before his arrest and (b) his requested $140 per-pill price.2
    Other    considerations   that   factored   into   the   court's   calculus
    included (c) Mills' agreeing that this was not the only time that
    he had smuggled oxycodone into the U.S.; (d) his having entered the
    U.S. from Canada 231 times in the 9-month period before his
    capture; (e) his offering no evidence that he had been legitimately
    employed when it mattered; and (f) his marijuana dealer tale
    holding no sway with the court.        For simplicity we refer to all
    this as the "(a)-(f) factors."            As for the CIs, true, their
    accounts about Mills' drug smuggling differed a bit. But they were
    remarkably in sync on the duration, method, and volume of his
    misadventures, and their accounts were perfectly consistent both
    with what had gone down on September 11 and with the full $369,203
    being tied to his drug dealing ways -- as the court supportably
    found.    Anyway, and as the court also credibly found, one could
    reasonably work out the drug quantity numbers using the (a)-(f)
    factors, without touching the CIs' narratives -- meaning their
    statements were merely "icing on the cake," as the court colorfully
    put it.     In other words, the CIs' comments played a peripheral
    rather than a starring role in the court's drug quantity analysis,
    2
    Remember how CI-1 said he had seen Mills with 50-100 pills
    every week for a year, which, using the higher number, works out to
    52,000 pills -- the court did not use that figure, or the figures
    offered by the other CIs.      Instead the court opted to divide
    $369,203 by $140 to get 2,637 pills -- a much smaller number than
    if it had used CI-1's figures, for example.
    -20-
    which also counts against Mills in the disclosure balancing.                   See
    Robinson, 
    144 F.3d at 107
    .
    Again, on the other side of the scale is the public
    interest in encouraging needed information and the informants'
    private interest in their safety.              See Tzannos, 
    460 F.3d at 139
    .
    And here the record supports the court's finding that revealing the
    CIs' identities posed an obvious risk to their safety.              Recall the
    prior publication of the CIs' reports on Mills and Smart's Facebook
    page.     Recall too the veiled threat Mills sent in a letter along
    with copies of his PSR.         The "feds" wanted to hold him culpable for
    additional drug quantity, he wrote, but "[t]hey will have a hard
    time" doing that "without someone testifying against me."
    The short of it is that the court did its job under the
    Roviaro    line       of   cases,   weighing    the   right   factors,   and   it
    defensibly found that -- given Mills' weak showing on one side, and
    the government's interest in preserving the CIs' anonymity on the
    other     --    the    scale   tipped    decidedly     against   disclosure.
    Consequently, we see nothing remotely resembling an abuse of
    discretion in the court's decision to deny Mills' disclosure
    motion.
    B. Calculation of the Drug Quantity Attributable to Mills
    Mills' second argument is a slight variation on the one
    we just rejected.          It goes something like this: The court, he says
    again, should have compelled the government to disclose the CIs'
    names.    Because the court did not, he quickly adds, it did not get
    -21-
    to see for itself how unreliable they were for the relevant-conduct
    calculation.     Yet, he concludes, the CIs were unreliable, and
    taking them out of the equation means that the amount of oxycodone
    attributed to him should have been limited to what was in his
    possession at his arrest.
    The law in this area is straightforward.            A sentencing
    court can make reasonable estimates of drug quantities, provided
    they are supported by a preponderance of the evidence, and we
    review those findings deferentially, reversing only for clear
    error.   See United States v. Bernier, 
    660 F.3d 543
    , 545-46 (1st
    Cir. 2011).    Also, the court can consider all kinds of relevant
    information regardless of admissibility at trial (including hearsay
    that has never been tested by cross-examination), provided it has
    "sufficient    indicia     of   reliability    to   support     its   probable
    accuracy."      U.S.S.G.    §   6A1.3(a);     United   States    v.   Cintrón-
    Echautegui, 
    604 F.3d 1
    , 6 (1st Cir. 2010); United States v.
    Brewster, 
    127 F.3d 22
    , 27-28 (1st Cir. 1997).           Last but not least,
    the court has considerable leeway in deciding whether particular
    evidence is reliable enough for sentencing purposes, and we review
    only for abuse of discretion.       See Cintrón-Echautegui, 
    604 F.3d at 6
    ; United States v. Green, 
    426 F.3d 64
    , 66 (1st Cir. 2005).
    With these background rules in mind, we can make quick
    work of Mills' argument.         For one thing, the court acted well
    within its discretion in denying Mills' disclosure motion, as we
    just saw.    For another, the CIs' statements regarding Mills' modus
    -22-
    operandi were detailed, mutually corroborative on key points, and
    compatible with the events surrounding his arrest3 -- and were
    therefore    sufficiently reliable.        See    Green, 
    426 F.3d at 67
    (concluding that statements of confidential informants that were
    sufficiently       detailed,     internally        consistent,         mutually
    corroborative, and compatible with other information presented were
    sufficiently reliable); see also United States v. Ventura, 
    353 F.3d 84
    , 88 (1st Cir. 2003) (similar).        On top of all this, the (a)-(f)
    factors arrayed above gave the court more than enough to make a
    reasonable drug quantity estimate.4       See United States v. Hall, 
    434 F.3d 42
    , 61-62 (1st Cir. 2006) (holding that the court did not err
    in   using   the   defendant's   total   drug    profits   as   a    basis      for
    3
    As a memory refresher for the reader, we again point out the
    commonalities the court supportably found among the CIs' accounts:
    Mills had been smuggling OxyContin for an extended time, at least
    since 2007; and he would collect cash from U.S. customers, exchange
    the money in Canada, buy pills there, and smuggle 100 or so pills
    back across the border by concealing them on or in his body. And
    Mills' acts on or around September 11 -- e.g., his crossing the
    border with 109 oxycodone pills in his alimentary canal -- pretty
    much mirrored the drug smuggling routine that the CIs had
    described.
    4
    Mills talks a lot about how he could have shown the CIs'
    unreliability if only he had had the chance to ask them questions
    like these: "How does he [CI-1] arrive at an estimate of 50-100
    pills? Does this same estimate apply for each time?"; "How can he
    [CI-2] possibly estimate the number of pills that Mills had"; "Upon
    what does he [CI-3] base his specific claims of the number of pills
    Mills was moving across the border? If it was two trips a week at
    up to 200 pills, then how can it have been up to 500 pills? For
    how many weeks was it 500 pills?"         But contrary to Mills'
    intimations, the court did not need answers to any of this: it
    suffices to say that the (a)-(f) factors gave the court an adequate
    way to calculate drug quantity, regardless of how the CIs
    responded.

    estimating drug quantity under the relevant conduct guideline).
    Ultimately, then, we see no clear error or abuse of discretion
    here.
    CONCLUSION
    Having found no basis for disturbing the sentence imposed
    by the district court, we affirm.
