    Before C UDAHY, K ANNE, and SYKES, Circuit Judges.
    K ANNE, Circuit Judge. Rickey Clark entered a blind guilty
    plea with respect to one count of conspiring to possess
    cocaine with intent to distribute, see 21 U.S.C. § 846, and
    one count of possessing cocaine with intent to distribute,
    see 
    id. § 841(a)(1).
    The district court determined by a
    preponderance of the evidence that Clark had possessed
    between 15 and 50 kilograms of cocaine. At the sentencing
    hearing, the government’s attorney repeatedly stated, in
    2                                                No. 07-1297
    error, that Clark was not subject to a mandatory minimum
    sentence. The judge considered the 18 U.S.C. § 3553(a)
    sentencing factors and imposed a sentence of 48 months’
    imprisonment. The very next day, the government filed a
    motion to correct the sentence, see Fed. R. Crim. P. 35(a),
    based on the fact that the court was required to impose a
    mandatory minimum sentence of ten years due to the
    quantity of cocaine Clark possessed, see 21 U.S.C.
    § 841(b)(1)(A)(ii). The court agreed that the mandatory
    minimum applied, and it amended the judgment to cor-
    rect the sentence. Because the district court acted within
    its power under Federal Rule of Criminal Procedure 35(a)
    when it corrected Clark’s sentence to reflect the statutory
    mandatory minimum, we affirm Clark’s sentence.
    I. H ISTORY
    Rickey Clark was charged in a multi-count indictment
    for his participation in a cocaine-distribution conspiracy.
    Without a written plea agreement from the government,
    Clark pled guilty to two of the charged counts: conspiring
    to possess cocaine with intent to distribute, 
    id. § 846,
    and
    possessing cocaine with intent to distribute, 
    id. § 841(a)(1).
    Clark did not admit that his offenses involved a
    particular quantity of cocaine, and he maintained through-
    out the proceedings that he possessed less than one
    kilogram. He also argued that the quantity of drugs at
    issue is an element of his 21 U.S.C. § 841 offense, and that
    the Fifth and Sixth Amendments precluded subjecting
    him to an enhanced sentence based on a drug quantity
    No. 07-1297                                               3
    that was not determined by a jury beyond a reasonable
    doubt. At the drug-quantity hearing, the district court
    pointed out that the Seventh Circuit has rejected similar
    constitutional arguments, and proceeded to decide the
    drug quantity by a preponderance-of-the-evidence stan-
    dard.
    The government called Juan Corral as a witness at the
    drug-quantity hearing. Corral was a cocaine dealer who
    had spent time in prison for drug-trafficking convictions.
    Clark was one of Corral’s repeat, multiple-kilogram
    customers between the months of February and June, 2002.
    During that time period, Corral’s sales of cocaine to
    Clark varied in quantity and frequency. Corral
    experienced some “droughts,” during which Corral’s
    suppliers could not provide him with cocaine. But, Corral
    explained, Clark was one of his “preferred” custom-
    ers—whenever Corral came off of a drought, Clark was
    one of the first customers he would call.
    Corral shared how he and Clark would arrange their
    meetings. They would talk over the phone and arrange a
    meeting place. They used code words to refer to kilograms
    of cocaine, including the terms “bench press,” “reps,” and
    “tickets.” Corral recounted one particular conversation
    he had with Clark, on June 5, 2002, in which the two
    men referred to the kilograms of cocaine as “tickets.” He
    said that Clark had asked for five tickets (kilograms), but
    that he was trying to get Clark to take six. Corral said he
    had no doubt in his recollection that on June 5, he and
    Clark talked about kilograms of cocaine.
    In recalling his encounters with Clark, Corral stated that
    the smallest amount of cocaine he sold Clark on one
    4                                               No. 07-1297
    occasion was three kilograms; the largest amount was
    around eight kilograms. The amount of cocaine that Clark
    most frequently purchased from Corral was five to six
    kilograms. Corral stated that he was “100 percent sure”
    that when Clark bought cocaine from him, he bought three
    or more kilograms at a time. Corral recalled, “to the best of
    [his] knowledge,” that he dealt with Clark about once a
    month. Based on those recollections, Corral estimated that
    he sold Clark “maybe 17 kilos” of cocaine during the five-
    month period. Corral thought that he dealt with Clark one
    time in February, and maybe twice in March. But he could
    not give estimates for April, May, or June. Corral did not
    remember the specific dates on which he sold cocaine to
    Clark. Corral explained how he arrived at the 17-kilogram
    estimate, which he felt was conservative: “I dealt with him
    from February 2002 to June 2002. And I [estimated] three
    keys a month, that would come out to 15. And I know
    for sure that he purchased at times more than three keys.”
    When considering the testimony, the district court
    explained that standing alone, Corral’s memory of the sales
    to Clark was not “good enough to send somebody away
    for.” The court then asked the government how many
    conversations between Corral and Clark they had
    recorded—“how many discussions about transactions is
    the Government actually able to prove with telephone
    calls?” The government then referred to the complaint
    affidavit, which detailed some of the wiretapped con-
    versations. During one such conversation, on May 14,
    Corral and Clark discussed five kilograms of cocaine.
    Another set of wiretapped conversations dealt with the
    June 5 transaction to which Corral testified and addressed
    No. 07-1297                                               5
    five to six kilograms of cocaine. The district court deter-
    mined that these two phone conversations corroborated
    Corral’s testimony that his drug deals with Clark hap-
    pened once a month.
    The government, however, did not introduce into
    evidence the actual transcripts or tapes of the wiretapped
    phone calls. The court instead relied on summaries of the
    wiretapped conversations contained in a complaint
    affidavit that was attested to by a drug-trafficking agent
    in the government’s efforts to show probable cause
    before a magistrate judge. Clark objected to the district
    court’s reliance on the complaint and its affidavit, because
    “defendants are not included in terms of drafting the
    complaint, can’t cross-examine the drafter of it, can’t
    make any changes, can’t make any suggestions. It’s the
    Government’s document which they submit.”
    The district court stated that the summarized wire-
    tapped conversations were “irrefutable evidence that
    [Clark] was discussing relatively large deals, that’s deals
    in the five-to-six kilogram range with Mr. Corral on two
    occasions.” Those conversations proved to the judge that
    Corral was “telling the truth in terms of the kind of cus-
    tomer that Mr. Clark was.” Even though the tapes were
    not in evidence, the district court “assum[ed] the Gov-
    ernment ha[d] this evidence that it [was] describing in
    the complaint.” The court explained that the govern-
    ment’s summary of the taped conversations was, to some
    extent, corroborated by Corral. Additionally, the court
    explained, “This is an official court document. So I’m
    assuming, for purposes of this drug quantity hearing,
    6                                               No. 07-1297
    where the standard is a preponderance of the evidence,
    and I don’t think rules of evidence strictly apply, that
    I can rely on the Government’s assertion that this com-
    plaint is based on surveillance.”
    Clark also argued that the court should discredit Corral’s
    testimony because Corral was an admitted perjurer who
    had a deal with the government that was contingent on
    him testifying to certain things. The district court did not
    agree, and found that Corral was “trying to be truthful
    and [ ] trying to be conservative,” even though his preci-
    sion was less than satisfactory. Thus, while Corral’s
    testimony alone was not precise enough, in the district
    court’s view, to justify a 15-kilogram drug-quantity
    finding, the combination of Corral’s testimony with the
    summarized wiretaps convinced the court that Clark’s
    offense involved more than 15 kilograms of cocaine.
    Shortly after the drug-quantity hearing, Clark appeared
    for sentencing on January 17, 2007. The district court
    began the sentencing hearing with a question about
    mandatory minimums: “Is there a mandatory minimum
    that applies in this case?” The Assistant United States
    Attorney (AUSA) replied, “There is not, Judge, and the
    presentence investigation report is incorrect in regard to
    that.” The AUSA explained that without the mandatory
    minimum, Clark’s sentencing range was 108 to 135 months’
    imprisonment; his Criminal History Category was I and
    his offense level was 31. The court repeated its question:
    “Okay. With no mandatory minimum?” The AUSA replied,
    “Right.”
    Clark argued for a sentence below the guidelines range
    because of his personal characteristics, his steady employ-
    No. 07-1297                                                7
    ment background, and the fact that he had no prior
    criminal convictions. Clark also argued that he deserved
    a sentence below the guidelines range because of the weak
    evidence demonstrating drug quantity. In response, the
    government urged the district court to sentence Clark
    within the guidelines range: “the Government would
    just argue that a guideline range is appropriate here,
    particularly given that the mandatory minimum does
    not apply . . . .”
    The district court viewed Clark’s cocaine-selling activi-
    ties as a “significant mistake,” but stated that the “rest of
    his life has been pretty good.” The court cited Clark’s
    minor criminal history, his “huge job stability,” and the
    fact that he is a family man, as factors indicating that he
    is a person who “appears to have a good life and a posi-
    tive life.” The court also took into consideration negative
    factors—such as Clark’s gambling problems and his
    new conviction for a serious felony drug offense—when
    analyzing the sentencing factors under 18 U.S.C. § 3553.
    The judge decided on a sentence of 48 months, to reflect
    the “seriousness of the offense,” while giving Clark “an
    opportunity to resume the positive aspects of his past
    life when he is released.”
    The very next day, the government submitted a motion
    to correct Clark’s sentence, pursuant to Federal Rule of
    Criminal Procedure 35(a). The government acknowl-
    edged the mistake it made at sentencing in insisting that
    no mandatory minimum applied to Clark’s offense. The
    government argued that the district court was required
    to impose the mandatory minimum prescribed by 21
    8                                                  No. 07-1297
    U.S.C. § 841(b)(1)(A)(ii), because of the 15 kilograms
    attributed to Clark’s offense by the court. The district court
    agreed that the court’s drug-quantity finding subjected
    Clark to the statutory mandatory minimum. The district
    court explained that, while “the court was able to deter-
    mine the drug quantity based on a preponderance of the
    evidence, [the court] does not believe that the evidence
    would have been sufficient to sustain a decision beyond
    a reasonable doubt.” The court exercised jurisdiction
    under Rule 35(a) and resentenced Clark to ten years in
    prison.
    II. A NALYSIS
    On appeal, Clark argues that the district court was not
    authorized under Rule 35(a) to change his sentence. He
    also argues that his Fifth and Sixth Amendment rights
    were violated when the district court found, by a prepon-
    derance of the evidence, facts that subjected him to a
    mandatory minimum sentence of ten years. Finally, he
    argues that the district court’s calculation of the quantity
    of drugs involved in his offense was clearly erroneous.
    A. The district court’s correction of Clark’s sentence
    Clark argues that the district court was not authorized
    to correct his sentence under Rule 35(a) to reflect
    the statutory mandatory minimum because, in Clark’s
    opinion, the Rule does not allow a correction in a case
    where the government waived the application of the
    mandatory minimum at the sentencing hearing. This
    No. 07-1297                                                 9
    presents a question of law that we review de novo. See
    United States v. Mendoza, 
    510 F.3d 749
    , 754 (7th Cir. 2007)
    (“Whether the district court followed the proper proce-
    dures after United States v. Booker in imposing [a] sentence
    is a question of law we review de novo.” (internal citation
    omitted)).
    Rule 35(a) allows for “Correcting Clear Error”: “Within
    7 days after sentencing, the court may correct a sentence
    that resulted from arithmetical, technical, or other clear
    error.” Fed. R. Crim. P. 35(a). The district court’s action in
    this case—correcting the sentence the day after it was
    imposed—falls within the parameters of Rule 35(a). The
    error was not arithmetical or technical, but instead was
    substantive—the court mistakenly failed to apply the
    mandatory minimum sentence for Clark’s conviction, as
    prescribed by Congress. See 21 U.S.C. § 841(b)(1)(A)(ii).
    The scope of Rule 35(a) is narrow; the advisory com-
    mittee notes indicate that the Rule should “extend only to
    those cases in which an obvious error or mistake has
    occurred in the sentence, that is, errors which would
    almost certainly result in a remand of the case to the trial
    court . . . .” Fed. R. Crim. P. 35 advisory committee’s note
    to 1991 Amendments. The Rule does not give the district
    court a second chance to exercise its “discretion with
    regard to the application of the sentencing guidelines,” nor
    does it allow for changes to a sentence based on the court’s
    change of mind. 
    Id. Additionally, the
    Rule should not be
    used in a way that relaxes “any requirement that the
    parties state all objections to a sentence at or before the
    sentencing hearing.” 
    Id. 10 No.
    07-1297
    Clark clings to this last limitation on Rule 35(a), and
    claims that the government lost its opportunity to argue
    for application of the mandatory minimum sentence by
    not raising the issue at sentencing, and more significantly,
    by affirmatively stating that no mandatory minimum
    sentence applied to Clark’s conviction. With this argument,
    Clark suggests that whenever the government (or the
    defendant, for that matter) makes a mistake at a sen-
    tencing hearing, the court is bound by that mistake and
    may not correct a sentencing error that stems from it.
    Clark’s position might make sense if applied to discretion-
    ary considerations and enhancements or reductions
    under the advisory guidelines—parties must state all of
    their objections to the multiple facets of a sentence at the
    sentencing hearing. See United States v. Porretta, 
    116 F.3d 296
    , 300 (7th Cir. 1997). Arguing after-the-fact, via a
    Rule 35(a) motion to correct a sentencing error, that the
    district court improperly applied a sentencing enhance-
    ment or reduction “flies in the face of the advisory com-
    mittee’s admonition that it ‘did not intend that the rule
    relax any requirement that the parties state all objections
    to a sentence at or before the sentencing hearing.’ ” 
    Id. (quoting Fed.
    R. Crim. P. 35 advisory committee’s note
    to 1991 Amendments).
    But the situation here is different because the mistake
    was more fundamental—the resulting sentence violated a
    legislative mandate requiring that persons convicted of
    Clark’s particular crime, with the amount of drugs in-
    volved, be imprisoned for a minimum term of ten years.
    See 21 U.S.C. § 841(b)(1)(A)(ii). The district court re-
    peatedly asked the AUSA whether there was a mandatory
    No. 07-1297                                                 11
    minimum it should factor into Clark’s sentence, but
    the AUSA erroneously stated that there was not. To
    bind the court to the government’s error would not only
    result in a windfall to this particular defendant—who is
    not unlike other defendants who were correctly sentenced
    to the mandatory minimum of ten years’ imprison-
    ment—but would also directly contravene congressional
    intent. Unlike the sentencing guidelines, which are advi-
    sory, see United States v. Booker, 
    543 U.S. 220
    , 264-65 (2005),
    statutory mandatory minimums are just as they sound—
    mandatory, see United States v. Cannon, 
    429 F.3d 1158
    , 1160
    (7th Cir. 2005). To allow a party’s blunder at sentencing to
    defuse the mandate of Congress—especially where the
    Federal Rules of Criminal Procedure provide a means for
    district courts to correct such blunders within seven days
    of the sentence—would convert individual lawyers
    into legislators each time a court mistakenly follows an
    illegitimate recommendation. The statements of the
    Supreme Court in Bozza v. United States, are equally
    pertinent here: “The Constitution does not require that
    sentencing should be a game in which a wrong move by
    the judge means immunity for the prisoner. . . . The
    sentence as corrected, imposes a valid punishment for
    an offense instead of an invalid punishment for that
    offense.” 
    330 U.S. 160
    , 166-167 (1947) (internal citations
    omitted).
    The mistake in this case that Clark desired to let lie
    would have been reversed on appeal—district courts
    must abide by statutory sentencing ranges. See United
    States v. Roberson, 
    474 F.3d 432
    , 434 (7th Cir. 2007) (“The
    Supreme Court’s decision in United States v. Booker, which
    12                                               No. 07-1297
    made the sentencing guidelines advisory, did not authorize
    district judges to ignore statutory sentencing ranges. . . .
    Booker confers no authority on judges to disregard stat-
    utes.” (internal citation omitted)). And the district court
    was well aware of its authority and the repercussions of
    such a mistake: “based on Seventh Circuit precedent,
    I have no choice but to impose the ten-year manda-
    tory minimum, and I think the failure to do so and the
    propriety of doing so is so clear that it would almost
    certainly result in a remand, which, I take it, is what I need
    to find in order to have jurisdiction under Rule 35 to
    correct the sentence.”
    Clark continues, however, that the AUSA’s denounce-
    ment during the sentencing hearing of a mandatory
    minimum foreclosed the possibility of a sentence correction
    under Rule 35(a) by way of the waiver doctrine. His
    argument is somewhat tenable in light of our language
    in United States v. Byerly, 
    46 F.3d 694
    , 699 (7th Cir. 1995).
    In Byerly, the government attorney told the district court
    that it was within the court’s discretion to impose a
    mandatory sentence. 
    Id. at 696.
    The government was
    wrong, but the government did not bring the error to the
    court’s attention until over two years later, after the
    defendant had (unsuccessfully) appealed his sentence,
    and after we issued our mandate affirming his convic-
    tion. 
    Id. at 697.
    The government filed a motion under the
    old version of Rule 35(a), which allowed the district court
    to “correct an illegal sentence at any time and [ ] correct a
    sentence imposed in an illegal manner within the time
    provided herein for the reduction of sentence,” that is,
    within 120 days of an affirmance of the judgment. 
    Id. No. 07-1297
                                                  13
    (quoting old Rule 35(a)). The government acted within
    the proper time frame under the old rule, but we
    decided that the district court could not correct the
    illegal sentence, notwithstanding the language of old
    Rule 35(a), because of the government’s waiver. 
    Id. at 699-
    700.
    An attorney cannot agree in open court with a
    judge’s proposed course of conduct and then
    charge the court with error in following that
    course. [The] AUSA [ ] bound his principal and
    client, the United States, to the position that the
    application of the Guidelines and a mandatory
    minimum sentence to Byerley’s conviction was
    discretionary with the district court. The govern-
    ment cannot now use old Rule 35(a) to overcome
    the errors of its agent.
    
    Id. at 700
    (internal citation and quotation marks omitted).
    Old Rule 35(a) was more expansive than the current
    version of the rule—allowing for the correction of an illegal
    sentence “at any time” up to 120 days after an affirmance
    or dismissal of the appeal. 
    Id. at 697.
    Thus, the Rule
    allowed for corrections of sentences long after their
    imposition, and in Byerly, the implications of such a broad
    grant of corrective power were clear. The Rule contem-
    plated allowing a party, the government, to sit back
    throughout the direct appeal process with the possibility
    of a Rule 35(a) correction in reserve. It made sense for us,
    in terms of judicial economy and the finality expectations
    of convicted defendants, to impose a limitation on old
    Rule 35(a) in a case where the government reversed the
    14                                                No. 07-1297
    position it advocated to the district court, years after
    sentencing.
    But that functional limitation is no longer necessary
    because Rule 35(a)’s revision includes a limitation that
    protects the dual concerns of judicial economy and
    finality: the district court must correct the sentence within
    seven days, see Fed. R. Crim. P. 35(a), and it may not
    correct the sentence after that time period, see United States
    v. Baldwin, 
    414 F.3d 791
    , 797 (7th Cir. 2005) (“The Supreme
    Court has held that these rules [including Rule 35(a)]
    operate to deprive the court of authority to act after the
    time period specified in the rule has elapsed.” (citing
    Carlisle v. United States, 
    517 U.S. 416
    , 428 (1996)) (overruled
    in part on other grounds by United States v. Parker, 
    508 F.3d 434
    , 441 (7th Cir. 2007)). Unfortunately for Clark, the
    doctrine of waiver is no longer necessary, nor applicable to
    the new Rule. Where a party makes a mistake at a sen-
    tencing hearing, which in turn leads to the imposition of a
    sentence that is clearly wrong—for example, a mistake in
    contravention of clear congressional intent or man-
    date—the district court may correct the sentence so long
    as the correction complies with Rule 35(a) and occurs
    within seven days. We emphasize that such mistakes
    might be made by either party—if a defendant did not
    realize at sentencing that he was not subject to a mandatory
    minimum sentence, but the court erroneously applied one,
    the defendant could make a motion for a corrected sen-
    tence within the seven-day time period. We also reiterate
    that the scope of Rule 35(a) is narrow, and our reasoning
    should not be read to allow parties to raise, after sen-

    at the sentencing hearing. See 
    Poretta, 116 F.3d at 300

    B. The imposition of a mandatory minimum sentence based on
    judge-found facts
    Clark contends that the quantity of drugs involved in
    his offenses should have been determined beyond a
    reasonable doubt, by a jury. We review this Apprendi issue
    de novo. United States v. Seymour, 
    519 F.3d 700
    , 709 (7th Cir.
    2008); see also Apprendi v. New Jersey, 
    530 U.S. 466
    , 490
    (2000). Clark was convicted under 21 U.S.C. § 841, which
    prescribes in its subsections escalating penalties for
    defendants depending on the quantity of a controlled
    substance the defendant knowingly or intentionally
    manufactured, distributed, dispensed, or possessed with
    intent to manufacture, distribute, or dispense. 21 U.S.C.
    § 841(a)(1), (b); see also United States v. Hernandez, 
    330 F.3d 964
    , 979-80 (7th Cir. 2003). Because the amount of
    cocaine involved in Clark’s conviction was over five
    kilograms, he was subject to a mandatory ten-year term
    of imprisonment. 21 U.S.C. § 841(b)(1)(A)(ii). This manda-
    tory term was below the twenty-year maximum term
    1
    This opinion has been circulated among all judges of this
    court in regular active service pursuant to Circuit Rule 40(e).
    No judge favored a rehearing en banc. Judge Flaum did not
    participate in the consideration of this case.
    16                                                No. 07-1297
    Clark could have received for a § 841 conviction absent
    any drug-quantity determination. See 
    id. § 841(b)(1)(C).
      Clark acknowledges that we have held on multiple
    occasions that judges may find facts, by a preponderance
    of the evidence, that subject a defendant to a statutory
    mandatory minimum. See United States v. Price, 
    516 F.3d 597
    , 605 (7th Cir. 2008); United States v. Jones, 
    418 F.3d 726
    ,
    732 (7th Cir. 2005); United States v. Knight, 
    342 F.3d 697
    ,
    714 (7th Cir. 2003); 
    Hernandez, 330 F.3d at 980-82
    ; see also
    United States v. Collins, 
    510 F.3d 697
    , 701 (7th Cir. 2007). We
    see no reason to depart from our precedent and continue
    to hold that “Apprendi has no application where a drug
    dealer is given a sentence at or below the maximum
    provided in § 841(b)(1)(C).” 
    Hernandez, 330 F.3d at 908
    ;
    see also United States v. Abdulahi, 
    523 F.3d 757
    , 760 (7th
    Cir. 2008) (“Apprendi has no application to cases like
    this one where the sentence is below the statutory maxi-
    mum.”).
    One of Clark’s arguments on this topic warrants brief
    consideration. Clark encourages us to rethink our prece-
    dent because the Second and Ninth Circuits have adopted
    contrary approaches to drug-quantity determinations
    under § 841. In United States v. Gonzalez, 
    420 F.3d 111
    , 133-
    34 (2nd Cir. 2005), the Second Circuit concluded that the
    “drug quantities specified in 21 U.S.C. § 841 are elements
    that must be pleaded and proved to a jury or admitted by
    a defendant to support any conviction on an aggravated
    drug offense, not simply those resulting in sentences
    that exceed the maximum otherwise applicable for an
    identical unquantified drug crime.” And in United States v.
    No. 07-1297                                                  17
    Velasco-Heredia, 
    319 F.3d 1080
    , 1085-87 (9th Cir. 2003), the
    Ninth Circuit decided that facts subjecting defendants
    to mandatory minimums under § 841 must be proven to
    a fact-finder beyond a reasonable doubt.
    “While we carefully and respectfully consider the
    opinions of our sister circuits, we are not bound by them.”
    United States v. Williams, 
    184 F.3d 666
    , 671 (7th Cir. 1999).
    “Our duty is to independently decide our own cases, which
    sometimes results in disagreements with decisions of
    the other circuits.” Atchison, Topeka & Santa Fe Ry. Co. v.
    Pena, 
    44 F.3d 437
    , 443 (7th Cir. 1994). We have carefully
    analyzed whether drug quantity constitutes an element
    of an § 841 offense that must be proven to a jury beyond a
    reasonable doubt, and have decided time after time that
    neither the statute, nor Apprendi and its progeny, dictates
    such a result. See, e.g., United States v. Martinez, 
    301 F.3d 860
    , 863-66 (7th Cir. 2002); see also 
    Abdulahi, 523 F.3d at 760

    61; 
    Hernandez, 330 F.3d at 980-81
    .
    C. The district court’s drug-quantity findings
    We review the district court’s determination of drug
    quantity for clear error. United States v. Artley, 
    489 F.3d 813
    ,
    821 (7th Cir. 2007). “This is a highly deferential standard of
    review and we refuse to ‘second-guess the sentencing
    judge.’ ” United States v. Hankton, 
    432 F.3d 779
    , 789 (7th Cir.
    2005) (quoting United States v. Cleggett, 
    179 F.3d 1051
    , 1059
    (7th Cir. 1999)). The government had the burden of proving
    drug quantity to the court by a preponderance of the
    evidence, United States v. McGowan, 
    478 F.3d 800
    , 802 (7th
    18                                                No. 07-1297
    Cir. 2007); United States v. White, 
    360 F.3d 718
    , 720 (7th
    Cir. 2004), but the evidence supporting the drug-quantity
    determination need not have been limited to evidence
    admissible at trial. 
    White, 360 F.3d at 720
    ; United States
    v. Galbraith, 
    200 F.3d 1006
    , 1011-12 (7th Cir. 2000).
    Clark argues that the district court should not have
    relied on the testimony of Juan Corral because Corral was
    an admitted perjurer and drug user who had lied previ-
    ously to protect his own interests. This argument fails
    because the district court specifically found Corral to be a
    truthful witness, despite his inability to remember specific
    details about his deals with Clark. A district court’s
    determination of witness credibility is “entitled to great
    deference and ‘can virtually never be clear error.’ ” White,
    
    360 F.3d 718
    , 720 (7th Cir. 2004) (quoting United States v.
    Blalock, 
    321 F.3d 686
    , 690 (7th Cir. 2003)). Further, a sen-
    tencing court may credit testimony that is “ ‘totally uncor-
    roborated and comes from an admitted liar, convicted
    felon, or large scale drug-dealing, paid government
    informant.’ ” 
    Id. (quoting Blalock,
    321 F.3d at 690); see also
    
    Galbraith, 200 F.3d at 1012
    ; United States v. Rodgers, 
    245 F.3d 961
    , 968 (7th Cir. 2001) (“[T]he district judge was free to
    credit Dexter. That Dexter was a convicted felon who stood
    to gain from his testimony against Rodgers is by no means
    a remarkable circumstance.”). Furthermore, it is clear from
    the record that Corral’s testimony about his sales to Clark
    never wavered. He maintained throughout the 17-
    kilogram estimate, and consistently explained that Clark
    usually purchased five kilograms, sometimes purchased
    three, and at least once purchased eight. Unlike the situa-
    tion in United States v. Beler, 
    20 F.3d 1428
    , 1433-34 (7th Cir.
    No. 07-1297                                                19
    1994), where the witness wavered in his testimony about
    drug quantity, Corral’s testimony remained constant.
    To compute his estimate of cocaine sales, Corral multi-
    plied the minimum number of kilograms he sold to Clark
    during a transaction (three kilograms) by the number of
    months he dealt with Clark (five months)—15 kilo-
    grams. Because he remembered selling Clark more than
    three kilograms “at times,” he added an additional two
    kilograms to his total calculation of 17 kilograms, which
    Corral stated was conservative. This method of computa-
    tion, assuming credibility and reliability of the witness,
    is permissible. A district court may “calculate drug quan-
    tity by taking a witness’s estimate of the amount of drugs
    she usually purchased and multiplying it by the number
    of times she bought drugs from the defendant.” 
    White, 360 F.3d at 720
    ; see also United States v. Durham, 
    211 F.3d 437
    , 444 (7th Cir. 2000).
    Granted, Corral could not recall the specific details of
    his deals with Clark, the exact number of occasions he
    sold cocaine to Clark, or the amount of cocaine involved
    in each sale. Clark argues that because Corral could not
    remember details, his testimony lacked the required
    “indicia of reliability” that would allow the district court
    to rely on his statements. See 
    Beler, 20 F.3d at 1433
    . Indeed,
    the district court agreed that Corral’s recollections were
    vague and not specific enough in themselves to support
    a drug-quantity finding of over 15 kilograms. However,
    the district court decided that the summaries of the
    wiretapped phone conversations—contained in the
    original complaint affidavit that was submitted to a
    20                                              No. 07-1297
    magistrate judge—corroborated Corral’s testimony. The
    two phone calls from May and June corroborated Corral’s
    testimony that Corral dealt with Clark about once per
    month and that Corral sold Clark kilogram quantities of
    cocaine.
    The transcripts of those conversations were not admitted
    into evidence, nor were the actual recordings—so Clark
    objects to the district court’s reliance on the complaint
    affidavit that summarized the conversations. The district
    court explained that because the standard was only a
    preponderance of the evidence, and the rules of evidence
    did not apply, it could rely on the government’s asser-
    tion in an official court document that the “complaint
    [was] based on surveillance.”
    Section 6A1.3(a) of the Guidelines allows sentencing
    courts to “consider information without regard to its
    admissibility under the rules of evidence applicable at
    trial, provided that the information has sufficient indicia
    of reliability to support its probable accuracy.” The com-
    plaint affidavit was a document presented to a magistrate
    judge and attested to by the drug trafficking agent. The
    district court was entitled to credit the complaint as an
    accurate summary of the government’s evidence about
    Clark. There was nothing suggesting that the com-
    plaint was unreliable or that it contained inconsistencies,
    which was the case in Beler, in which two sworn affidavits
    contradicted one 
    another. 20 F.3d at 1433-36
    ; see also
    
    Hankton, 432 F.3d at 790
    (stating that the defendant did not
    show how agent’s testimony about wiretapped conversa-
    tions was unreliable, other than the fact that testimony
    was inadmissible hearsay).
    No. 07-1297                                                21
    The summaries of the wiretapped conversations sup-
    ported Corral’s testimony, which never wavered with
    respect to how much cocaine Corral estimated he sold
    to Clark. We agree with the district court that the com-
    plaint affidavit contained the requisite indicia of reli-
    ability for the district court to factor its contents into the
    drug-quantity determination. Between Corral’s testimony
    and the corroborating summaries of the wiretapped
    conversation, the district court did not clearly err in
    finding by a preponderance of the evidence that Clark’s
    § 841 offense involved more than 15 kilograms of cocaine.
    III. C ONCLUSION
    The amended judgment of the district court correcting
    Clark’s sentence is A FFIRMED.
