    v.
    Charles Kroledge, Kathleen Kroledge
    a/k/a Kathy Kroledge, Tony L. Kroledge
    and Ethel Juanita Kroledge,
    Defendants-Appellants.
    Appeal from the United States District Court
    for the Northern District of Indiana, Hammond Division.
    No. 96 CR 33--James T. Moody, Judge.
    Argued November 4, 1999--Decided January 7, 2000
    Before Manion, Kanne and Evans, Circuit Judges.
    Kanne, Circuit Judge. Charles Kroledge, his wife
    Kathleen Kroledge, Charles’s brother Tony
    Kroledge and Tony’s wife Ethel Juanita Kroledge
    were convicted on December 1, 1997, of conspiracy
    to participate in mail fraud. Ethel and Kathleen
    Kroledge were also convicted of mail fraud. The
    Kroledges’ convictions resulted from the family’s
    attempt to defraud its insurer by filing false
    claims in conjunction with a fire, allegedly set
    by Charles Kroledge, that damaged Charles and
    Kathleen’s home. The four were indicted on the
    charge of using fire to commit a felony, but all
    were acquitted.
    The Kroledges do not appeal the merits of their
    convictions. Instead, they contend that their
    sentences were wrongly enhanced, because the
    district court included the arson as relevant
    conduct for purposes of enhancing each of their
    offense levels, and ask us to reconsider the
    standard of evidence required to include
    acquitted offenses as relevant conduct for the
    purpose of sentence enhancement. They also claim
    that the district court erred in enhancing their
    sentences for obstruction of justice. Finding no
    errors, we affirm.
    I.   History
    In May 1991, one of Charles and Kathleen
    Kroledge’s children accidentally shot a hole in
    the family’s television, causing it to spark.
    This accident led Charles’s brother Gilbert to
    joke that Charles and Kathleen, who were under
    considerable financial pressure to keep up with
    the mortgage payments on their house, would be
    better off if the house did catch fire. These
    events allegedly spawned a plan in Charles’s mind
    to burn down the house and use the insurance
    money to build a new house for the family.
    Shortly thereafter, Charles and Kathleen sought
    Gilbert and his wife Martha’s help in planning
    the fire, and the four engaged in activities such
    as experimenting with ways to start a fire and
    packing up mementoes, photographs and records.
    Charles’s brother Tony and his wife Ethel also
    became involved as Charles and Kathleen stored
    some of the boxes containing their possessions at
    Tony and Ethel’s house.
    On the morning of June 8, 1991, Charles told
    Martha that he and his wife intended to set fire
    to the house that night and that they would spend
    the evening with Tony and Ethel at the stock car
    races while the house burned. Sometime after 1:00
    a.m. that night, the Hobart, Indiana fire
    department responded to a fire at Charles and
    Kathleen Kroledge’s home. Although members of the
    Hobart Fire Department considered some of the
    damage to the house suspicious and worthy of
    arson investigation, the house was actually
    located in the jurisdiction of the neighboring
    town of Lake State, Indiana. Therefore, the Lake
    Station Fire Department was responsible for the
    investigation.
    Lake Station’s fire investigator Ken Corbeille
    who was inexperienced in arson investigation,
    focused on an electrical outlet rather than on
    other damage and determined that the fire was
    accidental. Corbeille then left the fire scene
    unattended for several hours. During this time,
    Gilbert Kroledge testified at trial that he and
    Tony Kroledge removed newspapers from inside the
    walls and among the furniture cushions of the
    couch where the fire started. These newspapers
    were allegedly planted by Charles to provide
    trailer for the fire.
    Charles and Kathleen Kroledge declared that
    their entire house and all their valuables
    (including those that they had stored with Tony
    and Ethel) had been destroyed by the fire. In
    addition, Kathleen and Ethel Kroledge forged
    false receipts for an apartment where Charles and
    Kathleen were supposedly residing during the
    reconstruction of their house. Ethel Kroledge
    asked the owner of the apartment that Kathleen
    claimed to be renting, Annette Mathews, whether
    she could use Mathews’s name on insurance claim
    forms and told Mathews to lie if anyone asked
    whether Kathleen and Charles were living with
    her. During this time, Charles, Kathleen and
    their family were actually living with Tony and
    Ethel Kroledge. When the fire was declared an
    accident, their insurer, State Farm Insurance
    Company ("State Farm"), reimbursed Charles and
    Kathleen for both their loss and their living
    expenses.
    In October 1991, Martha and Kathleen Kroledge
    had a falling out because Kathleen informed
    Martha’s husband Gilbert of an affair that Martha
    was having. Martha was enraged by this and told
    a relative about Charles and Kathleen’s
    activities. This relative contacted State Farm’s
    fraud investigators, who in turn contacted the
    FBI. The FBI contacted Martha, and the agency
    granted Martha and Gilbert immunity from
    prosecution in exchange for their cooperation in
    the investigation of the fire.
    In August 1993, an FBI investigator spoke with
    Charles and Kathleen Kroledge about the events
    surrounding the 1991 fire. Charles and Kathleen
    told this investigator that they attended stock
    car races that night and did not return home
    until 1:00 a.m. In November 1993, the same
    investigator spoke to Tony and Ethel Kroledge
    about their involvement in the fire. Neither Tony
    nor Ethel mentioned that Charles and Kathleen
    stayed with them during the time that the
    Kroledges were rebuilding their house, but the
    two did verify that Charles and Kathleen had
    attended stock car races with them on the night
    of the fire.
    During the 1993 investigation, Martha and
    Gilbert Kroledge secretly tape recorded
    conversations with Charles, Tony and Ethel. These
    conversations implicated each of the Kroledges in
    the scheme to defraud the insurer. Charles
    admitted that he burned his own house down. Tony
    and Ethel admitted that they had stored many of
    Charles and Kathleen’s possessions for them.
    On April 10, 1996, the four Kroledges--Charles,
    Kathleen, Tony and Ethel--were indicted on
    charges of conspiracy to commit mail fraud, mail
    fraud (on three counts) and using fire or an
    explosive to commit a federal felony. All four
    pleaded not guilty. After the return of a
    superseding indictment substituting certain
    mailings for which the mail fraud allegations
    would be based, trial commenced on November 17,
    1997.
    At trial, Charles Kroledge denied even
    discussing the possibility of starting a fire at
    his house. He also denied experimenting with ways
    to start a fire, and he testified that he
    attended stock car races on the night that the
    fire occurred. Kathleen admitted that she may
    have misrepresented her loss in her claim to
    State Farm but testified that she and Charles did
    not have financial problems. She denied lying to
    a State Farm investigator who asked her where she
    was living during the reconstruction of her
    house. State Farm claims adjuster Bob Bradley
    contradicted Kathleen’s story, claiming that
    Kathleen never informed him that she was living
    with Tony and Ethel. In addition, Annette Mathews
    testified that Ethel told her to tell any person
    who asked that the Kroledges were living in her
    apartment.
    Ethel Kroledge testified that she told the FBI
    investigator that she had lied about where
    Charles and Kathleen had lived during the
    rebuilding process, but the FBI investigator
    testified that she never admitted her lie prior
    to her testimony before a grand jury in 1994.
    Tony testified that he had no idea who lived in
    his house in 1991 because he worked nights. He
    also testified that Charles and Kathleen were
    with Tony at the stock car races on the night
    that the fire took place.
    The jury found all four Kroledges guilty of
    conspiracy to commit mail fraud. The jury also
    found Kathleen Kroledge guilty of two counts of
    mail fraud and Ethel Kroledge guilty of one
    count. The jury acquitted the Kroledges of all
    remaining counts, including using fire to commit
    a federal felony. At sentencing, however, the
    court found by a preponderance of the evidence
    that the Kroledges used fire as a part of their
    conspiracy to defraud State Farm, and therefore,
    the court used evidence of the arson as relevant
    conduct and applied this conduct to each
    defendant’s sentence. This evidence of relevant
    conduct led to a two-point enhancement of each
    defendant’s base offense level for reckless risk
    of serious bodily injury and another two-point
    enhancement for more than minimal planning. In
    addition, the court found that Tony, Kathleen and
    Charles had each obstructed justice by providing
    false testimony and lying to FBI investigators
    about their role in the conspiracy. Because of
    medical problems that she experienced, Ethel was
    separately sentenced. At her separate sentencing,
    the district court adopted the same findings
    about her behavior except that the court made no
    finding of perjury, and she was given a similar
    sentence. Charles, Tony and Ethel Kroledge were
    each sentenced to twenty-seven months
    imprisonment with a three year term of supervised
    release. Kathleen Kroledge was sentenced to
    thirty-three months imprisonment with a three
    year term of supervised release. Each of the
    defendants was ordered to pay State Farm
    $78,344.85 in restitution.
    II.   Analysis
    The Kroledges challenge the enhancement of their
    sentences on three grounds. First, they claim
    that the district court erred in enhancing each
    of their sentences for obstruction of justice.
    Second, they claim that the district court lacked
    sufficient evidence of arson to include it as
    relevant conduct for purposes of calculating
    their sentences. Third, they argue that the
    district court applied the wrong evidentiary
    standard in determining whether to include the
    arson as relevant conduct for the purpose of
    computing each of their sentences.
    Both the challenge to the district court’s
    enhancement to the Kroledges’ sentences for
    obstruction of justice and the challenge to the
    court’s inclusion of arson as relevant conduct
    are determinations made for the purpose of
    sentencing. We review sentence determinations for
    clear error. See United States v. Gwiazdzinski,
    
    141 F.3d 784
    , 788 (7th Cir. 1998). We will
    reverse on clear error only if we are left with
    a definite and firm conviction that a mistake has
    been committed. See United States v. Garcia, 
    69 F.3d 810
    , 819 (7th Cir. 1995).
    A.   Obstruction of Justice
    Each of the Kroledges challenges the enhancement
    of his or her sentence for obstruction of
    justice. Sentencing Guidelines sec. 3C1.1
    authorizes a two-point enhancement for
    obstruction of justice if the sentencing court
    finds by a preponderance of the evidence that a
    defendant "willfully obstructed or impeded . . .
    the administration of justice during the course
    of the investigation, prosecution, or sentencing
    of the instant offense." U.S. Sentencing
    Guidelines Manual sec. 3C1.1 (1997). "To
    establish an obstruction of justice, the
    sentencing court must make an independent factual
    finding that the defendant engaged in a willful
    attempt to provide false testimony." United
    States v. Smith, 
    103 F.3d 600
    , 606 (7th Cir.
    1996) (citation omitted). When a defendant
    objects to an enhancement for obstruction of
    justice, the district court must review the
    evidence and make an independent determination as
    to the existence of the willful obstruction of
    justice. See United States v. Menting, 
    166 F.3d 923
    , 929 (7th Cir. 1999). Since the court based
    its finding of obstruction against each Kroledge
    on different facts, we review each finding
    independently.
    1.   Charles Kroledge
    The sentencing court based its finding of
    obstruction of justice against Charles Kroledge,
    among numerous other items, on his testimony that
    Tony and Ethel Kroledge had no involvement in the
    scheme to defraud State Farm. Charles claims that
    this finding, which was based on the pre-sentence
    report, was inaccurate and did not meet the
    required specificity for findings of fact as to
    the willfulness and materiality of Charles’s
    testimony. We disagree.
    Even if the district court did not explicitly
    address the willful and material nature of
    Charles’s testimony, we may uphold the
    enhancement as long as the district court made a
    finding of obstruction that "encompasses all of
    the factual predicates for a finding of perjury."
    United States v. Craig, 
    178 F.3d 891
    , 901 (7th
    Cir. 1999) (quoting United States v. Dunnigan,
    
    507 U.S. 87
    , 95 (1993)). Charles’s testimony
    regarding Tony and Ethel Kroledge’s involvement
    in the conspiracy speaks to the guilt of
    Charles’s co-conspirators, Tony and Ethel, and is
    therefore a material obstruction. See 
    Craig, 178 F.3d at 901
    . Thus, to enhance Charles’s sentence
    for obstruction, Charles’s inaccurate testimony
    must have been made willfully, rather than as a
    result of mistake, faulty memory or confusion.
    See 
    Craig, 178 F.3d at 901
    . An enhancement
    authorized by sec. 3C1.1 may employ a defendant’s
    perjurious testimony, but we construe the
    Guidelines in such a way as to avoid punishing
    defendants for exercising their right to testify.
    See 
    Dunnigan, 507 U.S. at 96
    ; United States v.
    Emerson, 
    128 F.3d 557
    , 563 (7th Cir. 1997). In
    this instance, we find that the court correctly
    met this standard by focusing on elements of
    Charles’s testimony that did not reflect directly
    on his own guilt or innocence.
    Charles testified that no one, including Tony,
    entered the house after the arson investigator
    left the premises. This statement seems to have
    been made with the intent to show that his
    brother Tony had no participation in his scheme.
    However, Gilbert Kroledge testified that he and
    Tony Kroledge entered Charles’s house after the
    arson investigator left and removed newspaper
    from the couch and walls. Rather than claiming
    that his statements at trial were mistaken or the
    result of confusion, he still claims that his
    statements do not suggest that Tony and Ethel
    were not involved in the case. Because his
    statements were made to exculpate his family, we
    find no error in the court’s determination that
    Charles’s testimony formed the basis for a
    finding of obstruction.
    2.   Kathleen Kroledge
    The district court based its finding of
    obstruction against Kathleen Kroledge on her
    testimony that Tony and Ethel Kroledge were not
    involved in the conspiracy. The court found that
    she obstructed justice both by her trial
    testimony and by pretrial statements that she
    made to investigators. In her opening statement,
    Kathleen Kroledge confessed lying to
    investigators when she and Charles misrepresented
    their living expenses to State Farm. She now
    claims that her earlier false statements were
    immaterial and the finding that she perjured
    herself at trial was inaccurate.
    Kathleen Kroledge testified at trial that she
    told State Farm’s claim adjuster that she was
    staying with Tony and Ethel, rather than at an
    apartment as she had claimed. She also testified
    that she was often away from Tony and Ethel’s
    house, so Tony might not have been aware that she
    and Charles were living there. State Farm’s claim
    adjuster Bob Bradley testified that Kathleen
    never informed him that Charles and Kathleen’s
    family were residing with Tony and Ethel after
    the fire. In addition, Tony Kroledge testified
    that he told FBI investigators that he knew
    Charles and Kathleen Kroledge were living with
    his family while they rebuilt their house.
    Kathleen Kroledge’s testimony contradicts
    statements that she made to State Farm and to the
    FBI prior to trial and contradicts itself in
    several places. Given the testimony of the
    government’s witnesses at trial, we find that the
    trial court had sufficient evidence to conclude
    that the statements by Kathleen about Tony’s
    knowledge of her family’s presence in their home,
    as well as many other contradictory statements,
    constituted an attempt to obstruct justice, and
    we will not second guess the district court on
    such questions of credibility. Kathleen’s
    statements were material, as they would tend to
    influence the decisionmaking body to which they
    were addressed. See United States v. Wells, 
    519 U.S. 482
    , 483 (1997). Therefore, we find that the
    district court’s finding was accurate on the
    ground of her perjurious testimony and that its
    enhancement must be upheld without regard to the
    materiality of her earlier false statements.
    3.   Tony Kroledge
    The district court enhanced Tony Kroledge’s
    sentence because he provided an alibi for his
    brother and sister-in-law. Tony Kroledge argues
    that this finding was in error because any
    misstatements that he made to investigators
    occurred early in the investigation and were
    therefore immaterial. Application Note 6 to
    Sentencing Guidelines sec. 3C1.1 defines
    materiality as "evidence . . . that, if believed,
    would tend to influence or affect the issue under
    determination." U.S. Sentencing Guidelines Manual
    sec. 3C1.1 application note 6. Although
    misstatements made to investigators that do not
    force investigators to expend additional
    resources are not material, see United States v.
    Barnett, 
    939 F.2d 405
    , 407 (7th Cir. 1991),
    pretrial statements that significantly obstruct
    or impede an investigation are material and may
    serve as the basis for an enhancement. See 
    id. Tony Kroledge
    provided an alibi for his brother
    and sister-in-law by testifying that the two
    accompanied him to the stock car races on the
    night of the fire. Further, he corroborated
    Charles’s claim that Charles and Kathleen
    followed him home that night and did not find out
    about the fire until after 1:00 a.m. However, his
    own testimony and the testimony of some
    government witnesses suggest discrepancies in his
    story. Gilbert and Martha Kroledge both testified
    that they saw Charles and Kathleen Kroledge
    driving in the direction of the races on the
    night of the fire at an hour when Tony testified
    they were already with him. Tony Kroledge
    testified that it generally took thirty-five to
    forty minutes to return to his home from the
    races, yet he testified that on the night of the
    fire it took the Kroledges well over an hour to
    return home. In addition, Tony Kroledge testified
    on direct examination that he told the FBI
    investigator that Charles and Kathleen lived with
    him during the rebuilding of their home, but he
    also testified that he did not know at the time
    that they were living with him. Under cross-
    examination, Tony Kroledge admitted that he never
    told anyone that Charles and Kathleen lived with
    him until he testified so under oath before the
    grand jury.
    On appeal, Tony Kroledge explains, through
    counsel, that these statements were mistakes made
    by a simple man confused by the proceedings who
    was attempting only to protect his family.
    However, the district court found instead that
    these statements were made willfully in an
    attempt to obstruct justice. We review such
    findings of credibility with great deference and
    will not reverse unless we find clear error. See
    United States v. Hall, 
    101 F.3d 1174
    , 1179 (7th
    Cir. 1996). As such, the obstruction enhancement
    to Tony Kroledge’s sentence will remain
    undisturbed.
    4.   Ethel Kroledge
    The district court enhanced Ethel Kroledge’s
    sentence for obstruction of justice, but, unlike
    her co-defendants, the court based its
    enhancement on Ethel Kroledge’s pretrial conduct
    rather than her testimony. On appeal, Ethel
    Kroledge argues that her pretrial conduct did not
    significantly impede the government’s
    investigation into the fire and, therefore, was
    not material for the purposes of enhancing her
    sentence for obstruction.
    In its finding that Ethel Kroledge obstructed
    justice, the court adopted the finding of fact
    contained in the pre-sentencing report that Ethel
    Kroledge had obstructed justice by attempting to
    influence the testimony of a witness. Ethel
    Kroledge admitted in her testimony that she told
    FBI investigators that Charles and Kathleen lived
    with Annette Mathews during the period when their
    house was being rebuilt. Annette Mathews
    testified that Ethel Kroledge asked her to lie to
    the FBI and State Farm investigators and claim
    that Charles and Martha lived in their basement
    apartment during that period. Ethel Kroledge
    admitted that she asked Annette Mathews whether
    she could use her name on receipts that the
    Kroledges presented to State Farm.
    The presented testimony dispels any argument
    that Ethel Kroledge did not obstruct justice in
    an attempt to protect her brother and sister-in-
    law. However, she claims that her misstatements
    were not material because she later corrected
    them by telling the truth to FBI investigators.
    To determine the materiality of her conduct, we
    must review whether the district court correctly
    found that Ethel Kroledge’s actions significantly
    impeded the investigation of the Kroledges’
    conduct. See 
    Barnett, 939 F.2d at 407
    . In
    Barnett, we refused to uphold an enhancement for
    obstruction of justice based on a defendant’s
    pretrial conduct when the defendant’s only
    pretrial misstatement was that he denied
    committing the offenses about which he was
    questioned. See id.; see also United States v.
    Wells, 
    154 F.3d 412
    , 414 (7th Cir. 1998) (stating
    that obstruction of justice that "has no
    consequence . . . is not a permissible basis" for
    enhancement).
    In this case, however, Ethel Kroledge’s
    misstatements went well beyond a mere declaration
    of innocence. Instead, Ethel Kroledge concocted
    a false set of facts that led investigators
    toward a witness whom she had attempted to
    influence. As in Wells, Ethel Kroledge attempted
    to lead investigators on a "wild goose chase" in
    order to obscure evidence of her own criminal
    conduct. However, in this instance, unlike Wells,
    the evidence that Ethel Kroledge would obscure
    was not merely ancillary to questions of her (and
    her family’s) guilt; the activities she concealed
    were exactly those which led to Kathleen
    Kroledge’s and her own convictions for mail
    fraud. In circumstances such as these, we have
    found that such behavior was material, see United
    States v. Taylor, 
    135 F.3d 478
    , 483-84 (7th Cir.
    1998), and we have no question that Ethel
    Kroledge’s behavior significantly impeded the
    instant investigation. As such, her behavior was
    material for the purpose of determining whether
    her sentence should be enhanced for obstruction,
    and we will uphold the district court’s
    enhancement of her sentence.
    B.   Use of Arson as Relevant Conduct
    The Kroledges also argue that the district
    court erred when it found by a preponderance of
    the evidence that they had committed arson and
    that this arson could be used as relevant conduct
    for the purpose of computing their sentence. They
    argue that the district court lacked sufficient
    evidence to determine by a preponderance of the
    evidence that they committed arson, and in the
    alternative, they argue that under these
    circumstances the more rigorous "clear and
    convincing evidence" standard should have been
    applied instead of the "preponderance of the
    evidence" standard.
    All four Kroledges were acquitted of the
    federal crime of arson--using fire in the
    furtherance of a federal felony. However, the
    district court determined, for the purposes of
    sentencing, that a preponderance of the evidence
    indicated that the Kroledges had committed arson,
    and the court decided to use the acquitted
    offense of arson as relevant conduct for the
    computation of their sentences. In United States
    v. Watts, 
    519 U.S. 148
    , 149 (1997), the Supreme
    Court held that acquitted offenses may be used as
    relevant conduct for the purposes of computing a
    defendant’s sentence. The decision in Watts
    confirmed our own prior precedent, see United
    States v. Fonner, 
    920 F.2d 1330
    , 1332 (7th Cir.
    1990), which allowed such conduct to be taken
    into account. See 
    Watts, 519 U.S. at 149
    .
    Sentencing judges may use all information that
    they possess in order to properly compute their
    sentence. See 18 U.S.C. sec. 3661 ("No limitation
    shall be placed on the information concerning the
    background, character, and conduct of a person .
    . . for the purpose of imposing an appropriate
    sentence."). Because the relevant burden at
    sentencing is the "preponderance of the
    evidence," we allow evidence of acquitted conduct
    to be considered as long as the government has
    met the burden of proving by a preponderance of
    the evidence that defendants have engaged in the
    relevant conduct, see United States v. Porter, 
    23 F.3d 1274
    , 1277-78 (7th Cir. 1994), rather than
    applying the more stringent standard "beyond a
    reasonable doubt" required to convict a
    defendant. See 
    Fonner, 920 F.2d at 1333
    . Thus, we
    will uphold the sentences imposed by the district
    court whenever we determine that the government
    at trial met the applicable standard for proving
    that the defendants have engaged in the relevant
    conduct even if they were acquitted at trial
    under the stricter standard.
    1.   Relevant Burden of Proof
    We have held that a preponderance of the
    evidence is all that is required under the
    Sentencing Guidelines for a finding of fact. See,
    e.g., 
    Porter, 23 F.3d at 1277
    . Despite our clear
    precedent, the Kroledges urge us to consider the
    argument that a heightened standard of proof must
    be met under some instances "where a factual
    finding will result in a sentencing increase so
    great ’that the sentencing hearing can fairly be
    characterized as a tail which wags the dog of the
    substantive offense.’" United States v. Corbin,
    
    998 F.2d 1377
    , 1387 (7th Cir. 1993) (citations
    omitted). In support, the Kroledges cite United
    States v. Kikumura, 
    918 F.2d 1084
    , 1102 (3d Cir.
    1990), in which the Third Circuit required the
    higher standard of proof in a case where the
    sentencing court raised the defendant’s sentence
    from about thirty months to thirty years.
    In Corbin, we acknowledged the possibility that
    a higher standard might be appropriate in those
    circumstances where the government appeared to
    use the sentencing hearing to retry the
    substantive offense. In such circumstances, the
    district court might use its discretion to depart
    from the Sentencing Guidelines in such a way as
    to effectively sentence a defendant to the term
    that would have been appropriate had she been
    convicted of the substantive offense. As we noted
    in United States v. Rodriguez, 
    67 F.3d 1312
    , 1322
    (7th Cir. 1995), we have not yet been presented
    with an opportunity to consider whether, under a
    certain set of facts, such a heightened standard
    of proof may be appropriate. We are confident
    that these facts do not merit the imposition of
    the clear and convincing evidence standard.
    Here, the Kroledges were each acquitted of the
    charge of use of fire in the furtherance of a
    federal felony, pursuant to 18 U.S.C. sec.
    844(i), which provides that any person who
    "maliciously damages or destroys . . . by means
    of fire or an explosive, any building, vehicle,
    or other real or personal property . . . shall be
    imprisoned for not less than 5 years and not more
    than 20 years." Thus, if the Kroledges had been
    convicted of the federal arson charge, they would
    each serve between five and twenty years.
    Instead, by enhancing their sentences based on
    the relevant conduct of arson, each Kroledge is
    serving either twenty-seven or thirty-three
    months, which is roughly half of the minimum
    sentence that they would have received for the
    arson charge. As we noted in Porter, 
    see 23 F.3d at 1277-78
    , we have in many instances refused to
    adopt the Kikumura standard in cases where the
    sentence enhancement was more drastic than the
    enhancement at issue here. See 
    Rodriguez, 67 F.3d at 1323
    (51-63 months enhanced to life
    imprisonment); 
    Porter, 23 F.3d at 1276
    (92-115
    months enhanced to 137 months); United States v.
    Masters, 
    978 F.2d 281
    , 283-85 (7th Cir. 1992)
    (33-41 months enhanced to 40 years). Contrasting
    these cases with the facts of Kikumura, we find
    that this does not qualify as a rare instance
    where a higher standard might be justified.
    2.   Sufficiency of the Evidence
    The Kroledges also argue that, even under the
    preponderance of the evidence standard, the
    sentencing court lacked sufficient evidence of
    the arson to include it as relevant conduct for
    the purpose of enhancing their sentences. Because
    there is ample evidence available in the record
    on which to base a finding of arson, we
    understand this claim actually to imply that the
    district court committed clear error by believing
    the government’s witnesses and disbelieving the
    Kroledges’ witnesses.
    Determinations of credibility by the sentencing
    judge are entitled to great deference on review.
    See United States v. Anaya, 
    32 F.3d 308
    , 314 (7th
    Cir. 1994). When confronted with conflicting
    testimony, sentencing judges "are fully capable
    of considering the motivations of witnesses in
    weighing conflicting evidence and, because they
    have had an opportunity to assess the demeanor of
    the witnesses, are in a better position than this
    court to make credibility determinations." United
    States v. Griffin, 
    115 F.3d 1322
    , 1331 (7th Cir.
    1997). For this reason, when a defendant asks
    only that we reassess a credibility
    determination, the argument is "wasted on an
    appellate court," United States v. House, 
    110 F.3d 1281
    , 1286 (7th Cir. 1997) (citation
    omitted), unless a challenged witness’s testimony
    is shown to be inconsistent with contemporary
    documents or impossible. See, e.g., United States
    v. Grandinetti, 
    891 F.2d 1302
    , 1307 (7th Cir.
    1989).
    In this case, the Kroledges do not challenge
    any evidence presented by the government.
    Instead, they argue that the government’s
    evidence should not outweigh the evidence that
    the Kroledges presented. The government’s
    evidence of arson included testimony of at least
    three witnesses, each of whom told a consistent
    story, as well as such physical evidence as
    Charles and Kathleen Kroledge’s possessions pre-
    dating the fire, which had been stored with their
    family to preserve them, and the tape recordings
    made by Gilbert Kroledge, which capture
    admissions made by the Kroledges about the nature
    of the fire. We consider this evidence sufficient
    to support the district court’s determination.
    III.   Conclusion
    We find that the sentencing court correctly
    enhanced Charles, Kathleen, Tony and Ethel
    Kroledge’s sentences for obstruction of justice.
    In addition, we find that the district court’s
    decision to include the arson that the Kroledges
    were accused of committing as relevant conduct
    for the purpose of computing their sentences was
    correctly based on a preponderance of the
    evidence. Therefore, we AFFIRM the decisions of the
    district court.
