    The opinion of  this Court  issued on January  20, 1993,  is
    amended to delete, on page 21, line 10, the sentence which reads:
    "Further,   Elwell   himself   had   been
    recorded  as advising Polito  in the fall
    of  1988 that  Polito still  owed twenty-
    four  something,  a  figure that  in  the
    context  of  this  case   suggests  prior
    deliveries of $24,000 worth of cocaine."

    BOUDIN, Circuit Judge.  The grand jury indicted a number
    of  persons  for conspiring  to  distribute  cocaine and  for
    related offenses.  Several of  those indicted pled guilty but
    three were  tried jointly and convicted.    The appeal of one
    of those convicted  is decided today in  a separate decision.
    United  States v. Moran, No.  91-1772.  In  this decision, we
    address  the appeals  of the  other two  defendants  who were
    convicted  at  trial, together  with  the  appeal of  another
    defendant who pleaded guilty  but contests his sentence.   In
    two of the three cases we  affirm; and in one we remand  on a
    single issue for resentencing.
    I.
    We begin with a  brief outline of the facts  and history
    of the  case, reserving additional detail  for our discussion
    of individual claims of error.  The evidence submitted to the
    jury is, of  course, to be viewed in the light most favorable
    to  the verdict, the  jury being  accorded great  latitude in
    resolving  credibility  and  drawing  reasonable  inferences.

    , 1078-79 (1st
    Cir.), cert. denied, 
    492 U.S. 910
     (1989).
    On August  9, 1990,  the grand  jury indicted  the three
    appellants now in this  court (Richard Moretto, David Elwell,
    and  Hobart  Willis),  as  well as  six  other  persons,  for
    conspiracy  to distribute cocaine.   21 U.S.C.    846.  Other
    countsin the indictment chargedvarious of the defendants with
    -5-
    related  crimes.   Willis  and  several  others pled  guilty,
    Willis pleading to conspiracy and five counts of distribution
    under  21 U.S.C.     841.   After  trial the  jury  convicted
    Moretto,  Elwell, and  George  Moran (whose  appeal has  been
    separately decided) of conspiracy.   In addition, Moretto was
    found  guilty of witness intimidation, 18  U.S.C.   1512, and
    Elwell  of three counts of distribution, 21 U.S.C.   841, and
    one of filing a false tax return.  26 U.S.C.   7206.
    The critical testimony at  trial, except in the case  of
    Moran,  came primarily  from Mark  Polito, whose  account was
    bolstered  by  police  testimony  and tape  recordings.    He
    testified that during  the spring of 1988  he purchased ounce
    quantities  of  cocaine  every  week  or  two  from  Moretto.
    Because Moretto was scheduled to report to prison for a prior
    offense, Moretto--according to Polito's testimony--arranged a
    meeting between Polito  and Willis, "the man he [Moretto] got
    his stuff from."   At the meeting Willis agreed  to introduce
    Polito to  the  distributor  who  managed  Willis'  "northern
    territory."  A  few days  later Willis  introduced Polito  to
    Elwell and  for the  next few months  Elwell supplied  Polito
    with cocaine at the same price previously charged by Moretto.
    Polito  eventually  fell behind  in payments  and, under
    pressure  for payment  exerted by  Willis and  Elwell, Polito
    began to cooperate secretly with law enforcement authorities.
    Now buying  drugs  with  government  money,  Polito  recorded
    -6-
    conversations with Elwell and, on one occasion, brought a DEA
    undercover  agent to a meeting  with Elwell.   During a later
    sale,  Elwell  told  Polito  that  Willis  wanted  Polito  to
    "remember"  Moretto  at  Christmas,  Moretto  then  being  in
    prison.   This  reminder  was repeated  at  a later  meeting.
    Eventually Elwell became suspicious of Polito, ceased to deal
    with  him and in 1989 Willis began to supply Polito directly.
    The last reported transaction  occurred on February 16, 1989,
    when  Polito  paid Willis  part of  the  money still  owed to
    Elwell for prior purchases.
    Moretto  was released from prison  on June 5,  1990.  On
    June 11 and 12, 1990,  three telephone calls occurred between
    Moretto and  Polito, which  Polito secretly recorded.   Those
    calls, described  below, formed the basis  of the obstruction
    count against Moretto.  Nothing pertinent to the  charges was
    proved at trial  to have occurred after  June 12.   In August
    1990, the indictment was returned.
    Following Willis'  guilty plea and the  trial of Elwell,
    Moretto and Moran,  the defendants were  sentenced.    Willis
    and Moretto  were  found to  be  career offenders  under  the
    Sentencing Guidelines and each was sentenced to 210 months in
    prison.   Elwell  was sentenced  to 78  months.   The present
    appeals followed.

    II.
    Moretto's main  argument on appeal is  that the evidence
    of his adherence to the  conspiracy charged in the indictment
    was  too weak  to permit a  reasonable jury  to convict.   He
    further  argues that,  at most,  the evidence  showed several
    conspiracies  rather  than  the  single one  charged  in  the
    indictment,  and  he  asserts  that  this  supposed  variance
    between the conspiracy charged  and any conspiracy proved was
    prejudicial.    We  need  not treat  the  prejudice  argument
    separately because we conclude that the evidence  adequately,
    if  not amply, supported  the government's claim  of a single
    conspiracy  involving Willis  and  others  in  which  Moretto
    participated.
    Moretto does not dispute  that Willis directed a cocaine
    ring  but,  carving his  own role  into  phases, he  seeks to
    distance himself from  the ring.  Moretto's repeated sales of
    cocaine to Polito in the first part of 1988, which were amply
    proved, are claimed by  Moretto to fall outside the  ambit of
    the  Willis ring.1   Moretto  then argues  that he  could not
    1Moretto   places  stress  upon   a  statement   of  the
    prosecutor, made to  the judge in a pretrial conference, that
    the conspiracy charged by the  government began in March 1988
    when  Moretto  introduced Polito  to  Willis.   Although  the
    prosecutor did make such a statement--seemingly a slip of the
    tongue--the government's actual theory of  the conspiracy was
    that it reached  back to embrace Moretto's  earlier sales, as
    the  prosecutor made fairly clear  at the bottom  of the same
    transcript page  and even clearer  two pages  later.   There,
    responding to the judge's question ("The Government's  theory
    is that there  was some association between them [Moretto and
    -8-
    have  participated in the ring  from March 1988  to June 1990
    since he  was in prison.  As to the conversations with Polito
    on June 11-12, 1990, Moretto says that--even assuming them to
    be  obstructive--they  occurred well  after  the last  proved
    transaction of  Willis and Polito  on February 16,  1989, and
    therefore occurred after the conspiracy.
    The jury was entitled  to link these supposedly separate
    events together with  certain connecting  facts that  Moretto
    omits.   The drug  sales he made to  Polito during early l988
    were,  the  jury  could  have concluded,  based  on  supplies
    furnished  by   Willis;   Moretto,  according   to   Polito's
    testimony, said that  Willis was  "the man he  got his  stuff
    from."    The jury could  also have thought  that the Willis-
    Moretto relationship was a continuing one since, when Moretto
    was forced to  report to  prison, he introduced  Willis as  a
    substitute supplier.  Willis  then arranged for further sales
    to Polito at Moretto's  original price.  One act,  after all,
    can take  color from others,  and drawing such  inferences is
    the jury's task.
    During  Moretto's first  year in  prison there  is ample
    evidence of continued  sales by Elwell and  Willis to Polito.
    Moretto, although  in prison,  was  not entirely  out of  the
    picture: Elwell twice  told Polito that Willis  wanted him to
    Willis] prior  to that  introduction [of Polito  to Willis]),
    the  prosecutor stated, "Yes, from Moretto up the ladder  . .
    . ."
    -9-
    "remember" or not forget Moretto at Christmas.  While various
    inferences  can be drawn from these reminders, the jury could
    have believed that they reinforced Moretto's connection  with
    the  ongoing  conspiracy (even  assuming,  as the  government
    seems to do  in its brief, that Moretto was not a participant
    while  imprisoned).2   Specifically,  the evidence  increases
    the  likelihood, however  slightly, that  Moretto was  once a
    conspirator and might rejoin the conspiracy after prison.
    The jury could then  have concluded that, in making  the
    telephone calls to  Polito in June  1990, Moretto did  rejoin
    the conspiracy.   It is  true that  the time gap  between the
    last proved Willis ring transaction  in February 1989 and the
    calls in  June 1990  is substantial.   But the  jury was  not
    obliged to  believe that  a well  organized drug  ring, which
    enjoyed  a  "northern  territory"  and  remembered  a  former
    associate at Christmas, had suddenly expired.  When this same
    former foot soldier is discovered in June  1990 threatening a
    witness, who  is believed  likely to  testify  to the  ring's
    2The government's brief in  fact points to evidence that
    Moretto  while  in  prison  telephoned  Polito's  mother   to
    threaten Polito for failing to pay his drug-purchasing debts.
    That  evidence may  not have been  admissible because  of its
    hearsay  character--apparently  the  initial  source  of  the
    evidence was Polito's mother, who  did not testify.  However,
    this  evidence  is not  challenged  on this  appeal,  and the
    remaining evidence  against Moretto is adequate  even if this
    evidence, largely  embodied in a single  sentence of Polito's
    testimony, is ignored.
    -10-
    activities,  the  jury might  well  have  concluded that  the
    conspiracy was ongoing and the soldier had just reenlisted.
    Grunewald  v.  United  States,  
    353 U.S. 391
      (1957),
    heavily relied on by Moretto, does not forbid this inference.
    It  dealt  with  entirely  different  facts--specifically,  a
    conspiracy that had achieved its single objective well before
    the  acts of concealment that  were claimed to  extend it for
    purposes  of the statute  of limitations.3   Perhaps  more in
    point  is the statement in  United States v.  Mayes, 
    512 F.2d 637
    ,  642 (6th Cir.), cert. denied, 
    422 U.S. 1008
     (1975) that
    "[w]here  a conspiracy  contemplates a continuity  of purpose
    and  a continued performance of acts, it is presumed to exist
    until  there  has been  an  affirmative showing  that  it has
    terminated . . . ."  In all events, the jury in this case was
    certainly entitled  to infer from all  of the circumstances--
    apparent  size  of the  drug  ring,  its duration,  Moretto's
    threats, and the threats' references to others--that the ring
    continued and Moretto rejoined it.
    Separately,  Moretto claims  that the  evidence  did not
    support the jury's  guilty verdict against him on  the charge
    of  witness intimidation  under 18  U.S.C.    1512(b).   That
    statute in  pertinent part forbids any  act of "intimidation"
    3Similarly, in United States v. Serrano, 
    870 F.2d 1
     (1st
    Cir. 1989), statements sought to be introduced under  the co-
    conspirator exception to the  hearsay rule occurred after the
    fraudulent scheme had "collapsed."
    -11-
    done  with intent  to induce  anyone to  "withhold testimony"
    from  a grand jury or  other official proceeding.   The three
    telephone conversations in this  case, recorded by Polito and
    played to the  jury, are replete  with statements by  Moretto
    that the jury could reasonably  have found to be intimidating
    in both nature  and intent.   A brief  sampling of  Moretto's
    statements, omitting some rejoinders by Polito, conveys their
    flavor:
    "I just have a  message . . . .  You have
    one  chance to  hear  this  and then  its
    gonna be  somtin' that you  never want to
    hear  and it's  like a  hairline fracture
    away from it.   People knew  what's going
    on."
    "Mark, we got friends all over the place,
    right?  DEA,  state troopers,  everything
    . . . .  [Y]ou  don't seem  to understand
    that  everybody knows  that you  went and
    talked  [to law enforcement agents] . . .
    .  I got to call these people back .  . .
    .  [T]hey just  want some assurance  that
    nobody's going to no Grand Jury . . . ."
    The heart  of  Moretto's appeal  on this  count is  that
    during the  first of  the conversations  on  June 12,  Polito
    asked  Moretto if  Moretto  was threatening  him and  Moretto
    responded:  "No, I'm not.   I am not.  I'm  relaying indirect
    messages.  I'm  not threatening anybody.   I'm--I would never
    hurt  nobody.  I'm not that kind  of person."  The jury could
    reasonably view  this  statement, lodged  among  many  veiled
    threats,  as  a  boilerplate  disclaimer,  coupled  with  the
    intimation that others  ("I got to  call these people  back")
    -12-
    would inflict the harm if Moretto's warning were ignored.  If
    anything,  the statement enhances  the sinister  character of
    the conversation.4
    III.
    Willis, Elwell  and Moretto  each appeals his  sentence.
    We consider their respective claims in that order.
    Willis.  Willis was sentenced as a career offender under
    U.S.S.G.   4B1.1.  That  provision provides that a  defendant
    is placed in the  highest criminal history category and  that
    specified minimum  offense levels apply,  if three conditions
    are met:   first, the defendant must be at least 18 years old
    at  the time of the instant offense; second, the offense must
    be  a felony  that is either  a crime  of violence  or a drug
    offense; and third, the defendant must have "two prior felony
    convictions" for such offenses.  It is undisputed that Willis
    meets the  age condition,  that the  instant conviction is  a
    drug offense  and  that he  had five  prior convictions,  one
    state and  four federal, for five bank robberies committed on
    different dates during a brief period in 1968.
    Willis  argued  unsuccessfully  at  sentencing  that the
    prior bank  robberies should  be treated  as a  single felony
    4Moretto's  brief  adopts  by   cross-reference  Moran's
    argument   that   the  trial   judge  gave   a  supplementary
    instruction that  invited the  jury to ignore  the conspiracy
    charged  in  the  indictment   and  convict  of  a  different
    conspiracy.  That argument is considered and rejected  in our
    separate opinion in Moran.
    -13-
    because  the  definitions  provision  of  U.S.S.G.     4B  (
    4B1.2(3))  provides   in   part  that   "``two  prior   felony
    convictions' means .  . .  [that the convictions  were for  a
    crime of  violence or drug offense and  that] at least two of
    the  .  . .  convictions  are  counted separately  under  the
    provisions  of     4A1.1(a),  (b),  or  (c)."    This  latter
    provision,  designed to  determine the  number and  length of
    "prior  sentence[s]"  in  order  to   compute  a  defendant's
    criminal  history  category  under  U.S.S.G.    4A,  in  turn
    provides  in a  related  definition that  "[p]rior  sentences
    imposed  in related cases are  to be treated  as one sentence
    for  purposes  of     4A1.1(a),   (b)  and  (c)."    U.S.S.G.
    4A1.2(a)(2)  (emphasis  added).   The  commentary  to  that
    section, 
    id.,
     app. note 3, pertinently provides:
    [P]rior sentences  are considered related
    only if they resulted from  offenses that
    (1)  occurred on  the same  occasion, (2)
    were part of a  common scheme or plan, or
    (3)  were  consolidated   for  trial   or
    sentencing.
    Based on this language  Willis argued at sentencing that
    his five  bank robberies were  part of  a common plan  to rob
    banks and, in any event, that the sentences imposed--although
    not   formally   in   consolidated   cases--were   concurrent
    sentences,   part  of   the   same  bargain,   and  thus   in
    "constructively"   consolidated   cases.     Willis   further
    requested that,  if  his  proffer  of  these  facts  was  not
    accepted,  he  be   afforded  an   evidentiary  hearing   and
    -14-
    opportunity  for  fellow bank  robbers  to  testify to  their
    common  plan and  for  a former  attorney  to show  that  the
    sentences were concurrent and part  of the same plea bargain.
    The district  court declined  to hold an  evidentiary hearing
    and concluded that the bank robbery convictions were separate
    crimes.
    At  first  blush,  it   might  seem  unlikely  that  the
    Sentencing Commission intended  a defendant to escape  career
    offender status,  in the teeth  of two prior  convictions for
    different  bank  robberies  at  different  times  and places,
    simply because those  prior robberies were  assertedly linked
    by a further felony, namely, an overarching conspiracy to rob
    banks that  could literally  be  called a  "common scheme  or
    plan."  Of course,  two crimes might be so  closely related--
    for example, an  assault committed  in the course  of a  bank
    robbery--that  it  would  disserve  the plain  purpose  of  a
    "repeat offender"  statute to  treat convictions for  each as
    two  prior convictions.   But  five separate  bank robberies,
    committed with  the opportunity to pause  and reflect between
    them  and  memorialized  by   convictions,  are  surely  what
    Congress  had in mind as  identifying a career  offender.  28
    U.S.C.     994(h).    One  might  therefore  doubt,  at least
    initially, whether the Commission was aware that the contrary
    result would follow from its commentary language whenever the
    bank robberies were part of a common plan.
    -15-
    If  we were  satisfied  that the  outcome departed  from
    Commission intent, we might disregard the literal language of
    the commentary  and treat as  a single conviction  only those
    convictions  so closely  related  in time  and function  that
    separate treatment  would disserve the purpose  of the career
    offender provision.  Yet  a broader perspective suggests that
    the Commission, in defining  related convictions, did mean to
    adopt binding "rules of  thumb," such as this one, as well as
    the even  more mechanical rule that  convictions for entirely
    separate crimes should be treated as one if they happen to be
    consolidated for trial or  sentence.  U.S.S.G.   4A1.2(a)(2).
    In fact, the Commission in the same paragraph recognized that
    these rules  of thumb could understate  criminal history, and
    it said that the remedy in  such cases was for the sentencing
    judge to employ an upward departure.  Id.5
    To  conclude that the  Commission intended  the apparent
    result  of its literal  language does not  resolve the matter
    since  we  might  still decide  that  a  rule  of thumb  that
    produces  such a result is unfaithful to the guideline and to
    the career  offender  statute  that  lies  behind  it.    But
    5In the commentary paragraph containing both the "single
    scheme  or   plan"  and   the  "consolidated  for   trial  or
    sentencing" provisions, the Commission continued:  "The court
    should be aware  that there  may be instances  in which  this
    definition is overly broad and will result in [an inadequate]
    criminal history score  . . .  .  In  such circumstances,  an
    upward departure may  be warranted."  U.S.S.G.    4A1.2, app.
    note 3.
    -16-
    Congress in 28 U.S.C.    994(h) authorized the  Commission to
    develop  guidelines to assure  that career  offenders receive
    high sentences; and we  are loath to hold that  the mechanism
    developed by the Commission (and submitted to Congress) falls
    outside  that authority,  even if  there is  a Rube  Goldberg
    aspect to the use of overbroad rules of thumb tempered by the
    power  to depart.  The Second Circuit has treated the "common
    scheme or plan" language  as binding, while eloquently urging
    the  Commission to reexamine  its "related cases" commentary.
    United States Butler, 
    970 F.2d 1017
      (2d Cir.), cert. denied,
    
    113 S. Ct. 480
     (1992).
    Once  we  decide  that   the  "common  scheme  or  plan"
    definition is both intentional and valid, it follows that the
    "common scheme or plan" language should be given its ordinary
    meaning.  This same language is used in Fed. R. Crim P. 8 (to
    determine joinder) and there is no doubt that in that context
    a conspiracy to rob banks would constitute a common scheme or
    plan.   Willis offered to call fellow bank robbers to confirm
    that  his  robberies were  part of  the same  conspiracy, and
    there is  nothing implausible about his  proffer, however odd
    it might seem to  conduct this inquiry.  Other  circuits have
    required such evidentiary  hearings which, not  surprisingly,
    tend to  produce findings that the  multiple convictions were
    not part of a common scheme  or plan.  E.g., United States v.
    Chartier, 
    970 F.2d 1009
     (2d Cir. 1992).
    -17-
    For the reasons indicated, we feel constrained to accept
    the guideline commentary, to  conclude that the proffer could
    not  be  ignored,  and  thus   to  remand  Willis'  case  for
    resentencing.6   We do not, however, think  that the district
    court is required to hold an evidentiary hearing if the court
    concludes that it would impose the same sentence even without
    the "career offender" label.  The guideline commentary itself
    asserts  that the  rule of  thumb here  invoked by  Willis is
    overinclusive and  invites judges to depart  upward where the
    rule  of  thumb  operates  to  understate  criminal  history.
    Accordingly,  the requirements for departure are satisfied if
    the judge supportably concludes that--even assuming the truth
    of Willis'  proffer--five prior  bank robberies, united  by a
    conspiracy to rob banks, makes Willis deserving of a sentence
    similar to  that he would receive if  he were classified as a
    career offender.  U.S.S.G.   5K2.0.
    Whether or not  the outcome  proves to be  the same  for
    Willis, it is important  for future cases that the  integrity
    of the guideline regime  be preserved.  Under our  reading of
    the guideline commentary, the district court may not classify
    6The  government  says   that  the  district court  here
    "found" that there  was no common scheme or  plan and it says
    correctly  that  there  is  no automatic  requirement  of  an
    evidentiary hearing for every  contested issue.  But in  this
    case,  Willis' proffer  is not  implausible on  its face  and
    there  was  apparently  no  other  evidence  about  the  bank
    robberies.   As we read the  transcript, the district court's
    "finding" actually derived from a narrowing interpretation of
    the guideline language.

    Willis  as  a  career offender,  assuming  the  truth of  his
    proffer proposing to  show a  common scheme or  plan; but  we
    repeat (without prejudging  the facts of this  case) that the
    district court does have  authority to depart upward, subject
    to appellate review.  18 U.S.C.   3742(e)(3).  The net effect
    is  to increase the range of discretion of the district judge
    in these situations,  which may be  just what the  Commission
    intended.   As we have  noted, an evidentiary  hearing is not
    automatically  required in cases  like this  one--not because
    the judge can "find" no common scheme or plan in  the face of
    a proffer like  this one  and without a  hearing, but  rather
    because  the judge may depart  rather readily even  if such a
    scheme or plan is assumed.7
    Although Willis' case is to be remanded, we consider his
    other  claims of error, both for the guidance of the district
    court   and  to   reduce  the   need  for   further  appeals.
    Specifically,  Willis argues  that he  was wrongly  denied an
    evidentiary  hearing   on  two   issues   important  to   his
    sentencing, namely, the  amount of cocaine  for which he  was
    7We  reject  Willis'  further  argument  that  the  bank
    robbery convictions, even  though not formally  consolidated,
    should be deemed "constructively" consolidated because of the
    alleged plea bargain and concurrent  sentences.  The fact  is
    that  the cases  were not  consolidated.   Whatever anomalies
    result  from  the  accident  of consolidation  vel  non,  the
    situation   is  not   going  to   be  improved   by  treating
    unconsolidated   cases   as  "constructively"   consolidated,
    thereby broadening  beyond its language an  already overbroad
    rule of  thumb.  See  United States v.  Rivers, 
    929 F.2d 136
    (4th Cir.), cert. denied, 
    112 S. Ct. 431
     (1991).
    -19-
    responsible and his leadership status.  We think the district
    court properly resolved these matters.
    At the sentencing, the  judge determined that Willis was
    responsible for 2.2 kilos,  resulting in a base level  of 28,
    U.S.S.G.       2D1.1(a)(3),  (c)(8),   and  was  a   "leader"
    warranting an upward adjustment.  U.S.S.G.   3B1.1.  However,
    instead of  adopting the  resulting offense level,  the judge
    ruled that Willis was a  career offender, making him  subject
    (in light of the maximum sentence to which  he was liable) to
    a  base level of  32.  U.S.S.G.    4B1.1    The court reduced
    this  figure by  2 levels  for acceptance  of responsibility.
    The  court  then sentenced  Willis at  the  top of  the range
    provided  by  the sentencing  table  for a  criminal  with an
    offense level of  30 and  a criminal history  category of  VI
    (which  is automatic  under U.S.S.G.      4B1.1 for  a career
    offender).
    In finding  Willis  to be  a  leader and  computing  the
    amount of cocaine, the  judge relied upon information adduced
    at the trial of Willis' co-defendants and on other government
    tape  recordings  not  introduced   at  the  trial  but  made
    available for the sentencing.   On appeal Willis insists that
    he  was entitled to an  evidentiary hearing on  the amount of
    cocaine.   Neither the amount  of cocaine nor  the leadership
    finding affected the guideline  range adopted by the district
    court  since  the career  offender  guideline superseded  the
    -20-
    "otherwise  applicable  offense level."    U.S.S.G.    4B1.1.
    Nevertheless, because  the leadership role of  Willis and the
    amounts  of  cocaine  handled  by  his  ring  might  well  be
    pertinent  to  the district  court's  sentencing decision  on
    remand, we address Willis' objections.
    The law concerning the need for evidentiary hearings has
    been  left  primarily   to  development  through   individual
    decisions, which themselves  reflect the tension between  two
    attitudes: the  history  of almost  unreviewable trial  judge
    discretion in  sentencing and the present  specificity of the
    guidelines.  See U.S.S.G.    6A1.3.  Here, however,  there is
    no  need for any lengthy discourse on sentencing hearings.  A
    prima facie case existed, based on the presentence report and
    the evidence  adduced at the co-defendants'  trial, to regard
    Willis  as  playing  a leading  role  in  a  ring dealing  in
    substantial quantities of  cocaine.  At  no point did  Willis
    ever  specify or proffer evidence that would be adduced in an
    evidentiary hearing  to negate the amounts or Willis' role as
    leader.    Under these  circumstances, it  is patent  that no
    hearing  was required.   United States v.  Shattuck, 
    961 F.2d 1012
    , 1015 (1st Cir. 1992).   Lastly,   Willis  argues   that
    because the prior convictions were used to trigger the career
    offender  guideline,  the government  had  to  file a  notice
    specifying the  prior convictions before  Willis' guilty plea
    in  this case.  21 U.S.C.    851 (prior notice is a condition
    -21-
    of "increased punishment").   Willis'  argument that  section
    851  applies to  guideline  increases, as  well as  statutory
    maximums,  was rejected  by this  court in  United States  v.
    Sanchez, 
    917 F.2d 607
    ,  616 (1st Cir.), cert. denied,  
    111 S. Ct. 1625
     (1991).  We decline the invitation to reexamine that
    decision.
    Elwell.    Elwell  was   convicted  of  conspiracy,  two
    distribution counts, and wilfully  filing a false tax return,
    and he was sentenced to 78 months imprisonment.  The sentence
    was the minimum allowed under the guideline range in light of
    the finding  that  he had  distributed  at least  500  grams.
    U.S.S.G.    2D1.1(a)(3), (c)(3).
    Elwell first contests the finding that he did distribute
    at least 500 grams.  He  admits the distribution to Polito of
    about  3 ounces  (approximately  84 grams)  for which  he was
    convicted; indeed, Elwell admitted  at sentencing that he had
    sold  more to Polito without  specifying a number.   At trial
    Polito testified  that, apart from  the 3 ounces,  Elwell had
    delivered "18, maybe 20"  ounces of cocaine to  Polito during
    the summer of 1988.  The judge accepted this evidence despite
    Elwell's denial at the sentencing hearing that he had sold so
    large a  quantity.  Even the  low-end figure of 18  ounces is
    504 grams, exceeding the guideline minimum of 500 grams.
    The  critical facts by which a  guideline range is fixed
    must  be proved  by a  preponderance of  the  evidence, e.g.,
    -22-
    United States v. Blanco,  
    888 F.2d 907
    , 909 (1st  Cir. 1989).
    While inviting us to raise or at least stiffen this standard,
    Elwell's  main argument  is  that Polito's  estimate was  too
    casual  to  support the  drastic  increase  in sentence  that
    results  for  distributing  18  rather than  3  ounces.    He
    stresses  the fact that Polito was himself a user during this
    period  and admitted  to  hazy recollections  or mistakes  in
    other  testimony.   Combining these  arguments, he  argues on
    appeal that the judge's determination was  clearly erroneous,
    the standard properly  applied on review.   United States  v.
    Aymelek, 
    926 F.2d 64
    , 69 (1st Cir. 1991).
    We disagree.   The district court,  which heard Polito's
    testimony at  trial and Elwell's testimony  at the sentencing
    hearing,  was entitled  to  choose between  them.   The  time
    period  over which  Elwell  supplied Polito  and the  size of
    Polito's purchases were also  consistent with the 18-20 ounce
    figure.  Against this  backdrop and in light of  the standard
    of review, we find  no error.  This conclusion  also disposes
    of Elwell's claim  that the larger  ounce figure was  wrongly
    used  in  determining  the  amount of  unreported  income  in
    sentencing under the tax count.
    Elwell  objects  lastly  to  the  special  condition  of
    supervised release that requires him to submit to random drug
    testing,  as well as drug and  alcohol treatment, as directed
    by the Probation  Service.   Elwell objects that  his use  of
    -23-
    drugs (cocaine  and previously  amphetamines) lay 5  years or
    more  in the past, that nothing else supports this condition,
    and that  supervised release conditions  should "involve[] no
    greater  deprivation of liberty than necessary   . . . ."  18
    U.S.C.    3583(d)(2).  We  believe that the  drug testing and
    treatment requirement--if  deemed necessary by  the Probation
    Service--lay  well  within the  district  court's discretion,
    given Elwell's past  use and  past dealing in  drugs.  As  to
    alcohol,  the failure  of Elwell  to raise this  objection at
    sentencing  or by  post-trial motion  makes it  impossible to
    assess  the  district  court's  reasons for  adding  in  this
    condition  and,   in  our  view,  this   failure  waived  the
    objection.
    Moretto.   Moretto's sentence was based  on the district
    court's  finding  that  he  should  be  treated  as a  career
    offender.  His  record showed two state court convictions for
    assault and related conduct in October 1987 and February 1990
    respectively and a drug conviction for possession with intent
    to  distribute in March 1988.  In the district court, Moretto
    argued that  the assault convictions were  misdemeanors under
    state  law,  but the  trial judge  found  them to  qualify as
    felonies for guideline purposes.  See U.S.S.G.   4B1.2,  app.
    note  3 (prior felony  conviction includes offense punishable
    by  more than one year imprisonment even if not designated as
    a felony).
    -24-
    On appeal,  Moretto asserts that the  trial court relied
    on  the  two   state  assault  charges  to  find   two  prior
    convictions.  Moretto then argues that while the October 1987
    conviction  may be  a "prior"  felony conviction,  the latter
    assault conviction in February  1990 occurred after the start
    in 1988 of the conspiracy for which  he was convicted in this
    case.   In reply, the  government says that  this argument is
    waived  because not made below; that in any event the instant
    conspiracy  continued  after  the February  1990  conviction,
    making it a prior  conviction under the guidelines;  and that
    the  first  assault   conviction  and  the   drug  possession
    conviction  both  remain  even   if  the  second  assault  is
    disregarded.
    Waivers  are occasionally forgiven  and the government's
    reliance on  the March 1988 drug  conviction could presumably
    be assailed on  the same  ground that Moretto  now offers  to
    exclude  the  February  1990  conviction  from consideration,
    namely, that it occurred  after the instant conspiracy began.
    But  we   think  the  ground  is   clearly  wrong:  continued
    participation  in  a  conspiracy after  a  felony  conviction
    renders that conviction  a prior felony conviction.   This is
    apparent from  both the letter and intent  of the guidelines,
    U.S.S.G.   4B1.2(3)("defendant committed the  instant offense
    subsequent to sustaining at least two felony convictions  . .
    -25-
    . ."), and thus there was no error in sentencing Moretto as a
    career offender.
    The  judgments are  affirmed except  as to  Willis whose
    case  is remanded  for resentencing  in accordance  with this
    opinion.
