    ____________
    Before FLAUM, KANNE, and SYKES, Circuit Judges.
    KANNE, Circuit Judge. On October 6, 2004, a grand jury
    in the Western District of Wisconsin returned an 18-count
    superseding indictment charging narcotics violations
    against seven individuals including Raul and Ricardo
    Romero. The indictment resulted from a two-year joint
    federal, state and local law enforcement investigation into
    drug trafficking by the “Romero organization” in Madison,
    Wisconsin. Several individuals in the Romero organization
    are brothers including Raul and Ricardo Romero. The
    government alleged that Raul Romero was a drug dealer
    in the organization while Ricardo Romero was a drug
    courier.
    2                                  Nos. 05-3294 & 05-3681
    Raul Romero pled guilty to one count of possession of
    cocaine with intent to distribute in violation of 
    21 U.S.C. § 841
    (a)(1), and was sentenced to 130 months’ imprison-
    ment. Ricardo Romero was found guilty by a jury of one
    count of conspiring to distribute cocaine in violation of
    
    21 U.S.C. § 846
    , one count of possession of five grams or
    more of cocaine base with intent to distribute in viola-
    tion of 
    21 U.S.C. § 841
    (a)(1), and possession of cocaine with
    intent to distribute in violation of 
    21 U.S.C. § 841
    (a)(1).
    The district court sentenced Ricardo Romero to a term of
    151 months’ imprisonment. Ricardo Romero appeals his
    conviction and both Ricardo and Raul Romero appeal their
    respective sentences. We affirm both the conviction and
    sentences.
    I. BACKGROUND
    A. Raul Romero
    At his plea colloquy, Raul Romero admitted to selling
    cocaine to an undercover police officer on April 7, 2004.
    The undercover officer had set up a controlled drug buy
    as part of the then ongoing law enforcement investiga-
    tion of the Romero organization. Raul Romero sent Joshua
    Carrasquillo, another member of the Romero organization,
    to deliver 27.9 grams of cocaine to the undercover officer
    in exchange for $850. The transaction occurred in the
    parking lot of the Kennedy Heights apartment complex
    in Madison. Carrasquillo also discussed the possibility of
    future drug transactions with the undercover police officer
    on behalf of Raul Romero.
    In the Presentence Investigation Report (“PSR”), the
    Probation Officer determined that Raul Romero was
    responsible for selling drugs from at least November 2003
    through April 2004. The Probation Officer calculated
    Raul Romero’s relevant conduct at 2.5 kilograms of cocaine
    Nos. 05-3294 & 05-3681                                  3
    and, applying the November 2004 Sentencing Guidelines,
    his base offense level was 28. See U.S.S.G. § 2D1.1(c)(6).
    Raul Romero objected to the PSR arguing that he was
    responsible for less than two kilograms of cocaine. The
    government countered that the 2.5 kilogram amount was
    a conservative estimate and the reality was that Raul
    Romero was responsible for significantly more drugs than
    the 2.5 kilograms of cocaine set forth in the PSR. The
    government, however, chose not to pursue an amount
    above and beyond the 2.5 kilograms at sentencing. The
    government did argue that Raul Romero should not re-
    ceive a reduction for acceptance of responsibility if he
    contested the 2.5 kilograms.
    Raul Romero continued in his objection to the PSR and
    the district court conducted a sentencing hearing on July
    20, 2005. The government presented in-court testimony
    from a Drug Enforcement Administration (“DEA”) agent
    who participated in the Romero investigation. The DEA
    agent testified as to the government’s investigation of
    Raul Romero including undercover drug purchases as
    well as physical and electronic surveillance. The govern-
    ment also provided in-court testimony from cooperating
    witness Jose David Suarez and the prior grand jury
    testimony of cooperating witnesses Jacourtney Ticey and
    Danny Turner. Suarez, Ticey, and Turner testified as to
    their participation in, and witnessing of, drug transac-
    tions and other drug related activities involving Raul
    Romero.
    The district court determined that the government had
    met its burden and found Raul Romero responsible for 2.5
    kilograms of cocaine. The court also held that Raul Romero
    was not eligible to receive a reduction for acceptance of
    responsibility. In explaining her decision, the district
    court commented:
    4                                    Nos. 05-3294 & 05-3681
    I mean it’s very clear to me that, Mr. [Raul] Romero,
    you were involved in a lot more than the quantity that
    the government said it could prove against you and the
    quantity that was listed in the Presentence [Investiga-
    tion] Report. And in contesting that, you were really
    denying responsibility for your involvement in the
    amount of cocaine for which you’re responsible, and
    I’m not going to give you an adjustment for acceptance
    of responsibility. You knew the risk. You went ahead
    and took it. Well, this is what the consequence is.
    Tr. at 99-100, July 20, 2005. The district court then
    calculated Raul Romero’s advisory Sentencing Guideline
    range. Raul Romero’s base offense level was 28 for the
    2.5 kilograms of cocaine and this was enhanced by two
    levels for obstruction of justice1 for a total offense level of
    30. With his criminal history category of III, Raul Romero’s
    resulting advisory Sentencing Guidelines range was 121 to
    151 months’ imprisonment. The district court, after
    considering the sentencing factors set forth in 
    18 U.S.C. § 3553
    (a), imposed a sentence of 130 months’ imprison-
    ment.
    B. Ricardo Romero
    Ricardo Romero’s conviction is based on his April 30,
    2004 delivery of a blue cookie tin that contained cocaine
    and cocaine base. The government’s theory of the case
    was that Ricardo Romero transported the drugs to his
    mother’s apartment on Troy Drive in order to facilitate
    a drug sale between Raul Romero and Danny Turner. As
    1
    The two level enhancement for obstruction of justice was
    assessed against both Raul and Ricardo Romero for their
    participation in an assault on a potential government witness.
    Neither challenged the obstruction of justice enhancement in
    their appeal so we shall not discuss it further.
    Nos. 05-3294 & 05-3681                                  5
    Ricardo Romero’s present appeal attacks the validity of
    both his conviction and sentence, we recount the evidence
    presented at trial and sentencing.
    On the morning of April 30, 2004, Mary Jane Almeida,
    Ricardo Romero’s girlfriend at the time, left her home and
    went to her volunteer job at a local elementary school.
    Almeida was seventeen and a high school senior. Almeida
    and Ricardo Romero had known each other for approxi-
    mately one and one-half months prior to April 30, 2004.
    Ricardo Romero, who had spent the prior evening at
    Almeida’s home, remained at Almeida’s home while she
    was at her job. Almeida drove Ricardo Romero’s blue
    Oldsmobile Aurora to the volunteer job. She returned to
    her home at approximately 11:30 a.m. Almeida and
    Ricardo Romero had no prior joint plans to leave her home
    after she had returned from her volunteer job. In fact,
    Almeida had her own possible plans of going back to her
    volunteer job later in the day without Ricardo Romero.
    Ricardo Romero then received a telephone call. Almeida
    testified, based on her viewing of the caller ID, that the
    telephone call had come from Ricardo Romero’s mother’s
    apartment on Troy Drive. The call lasted a few minutes
    and promptly thereafter Ricardo Romero and Almeida
    left for the mother’s apartment. Almeida testified that
    Ricardo Romero was holding the blue cookie tin when they
    left for the Troy Drive apartment. She drove Ricardo
    Romero’s Oldsmobile Aurora accompanying him to the
    apartment.
    Ricardo Romero and Almeida arrived outside the Troy
    Drive apartment at approximately 11:45 a.m. According to
    Almeida, upon arriving, but before exiting the Oldsmobile,
    Almeida gave the car keys back to Ricardo Romero.
    However, he immediately returned the car keys to her
    along with the cookie tin and some clothing asking
    Almeida to hold onto these items for him. Almeida put the
    6                                 Nos. 05-3294 & 05-3681
    cookie tin, keys and clothing into her large size purse and
    then she and Ricardo Romero walked into the apartment
    building. Upon entering the apartment building, Ricardo
    Romero “grabbed” the cookie tin from Almeida’s purse
    and then they continued to the apartment. Tr. at 114-15,
    June 20, 2005.
    Several people were in the mother’s apartment when
    Almeida and Ricardo Romero arrived including Raul
    Romero, Ricardo Romero’s mother, Ricardo Romero’s
    nephews, and Turner. Turner testified that he had gone
    with Raul Romero to the Troy Drive apartment with the
    intent of receiving cocaine from Raul Romero. Turner had
    already paid Raul Romero for one-eighth of an ounce of
    cocaine. Raul Romero informed Turner that he did not
    have any cocaine when he arrived at the apartment and
    they needed to wait for cocaine to be delivered. Turner and
    Raul Romero waited for approximately five to ten minutes
    and then Ricardo Romero and Almeida arrived. Upon
    arriving, Ricardo Romero gave the cookie tin to Raul
    Romero and then Raul Romero went to the bathroom
    with the cookie tin. Raul Romero then gave cocaine to
    Turner and Turner left the apartment. The cookie tin
    was returned to Ricardo Romero who gave the cookie tin
    back to Almeida. Almeida placed the cookie tin back in
    her purse and she and Ricardo Romero left the apart-
    ment. Almeida was sitting on the living room couch
    reading a magazine during her time in the apartment.
    Law enforcement involved in the Romero organization
    investigation were performing surveillance of the Troy
    Drive apartment on April 30, 2004. Officers witnessed
    Turner leave the apartment building. They also witnessed
    Ricardo Romero and Almeida enter and exit the apart-
    ment building. Law enforcement followed Ricardo Romero
    and Almeida as Almeida drove Ricardo Romero’s car away
    from the mother’s apartment. The police officers then
    executed a valid traffic stop and valid search of the
    Nos. 05-3294 & 05-3681                                 7
    Oldsmobile. Almeida’s purse was on the backseat of the
    Oldsmobile. The police discovered the cookie tin contain-
    ing the cocaine and cocaine base. Ricardo Romero and
    Almeida were then arrested. During its subsequent
    investigation, the government concluded that Almeida was
    neither aware of the drugs in the cookie tin nor involved
    in any drug transactions and therefore she was not
    charged in this case.
    At trial, the government provided testimony from
    cooperating witness Suarez to prove that Ricardo Romero
    was actively involved in drug transactions in the Romero
    organization and thus aware that he was delivering drugs
    to Raul Romero on April 30, 2004. Suarez was a drug
    dealer who purchased drugs from various members of
    the Romero organization including Raul Romero. Suarez
    testified that he witnessed Ricardo Romero deliver co-
    caine to Raul Romero in the parking lot of an apartment
    building on Badger Road in Madison sometime in late
    Fall 2003. Suarez also testified that he saw Raul Romero
    give money to Ricardo Romero on several occasions.
    Ricardo Romero countered that he had no knowledge
    that there were drugs in the cookie tin. His strategy at
    trial was to attack the credibility of the government’s
    witnesses on cross-examination. With Almeida, he focused
    on inconsistencies in her story and the fact that her
    recollection of events had changed during her various
    interviews with the police. He also attempted to impeach
    Almeida with her prior statement from a state court
    proceeding. The district court sustained the government’s
    objection to this line of questioning concluding that the
    state case was an unrelated collateral matter that
    would unduly confuse the jury. Ricardo Romero also
    suggested at closing argument that Almeida was the actual
    drug courier for Raul Romero.
    With Turner and Suarez, Ricardo Romero attacked their
    credibility by pointing out they reached agreements with
    8                                 Nos. 05-3294 & 05-3681
    the government that would lower their sentences in
    exchange for their cooperation. Ricardo Romero also
    attacked Suarez’s testimony by noting that he had initially
    failed to make any mention of Ricardo Romero in his prior
    statements to law enforcement. Ricardo Romero argued
    that Suarez had provided the story about witnessing the
    drug delivery in Fall 2003 after law enforcement had
    pressed him looking for information on the eve of Ricardo
    Romero’s trial.
    Ricardo Romero also introduced evidence that he was
    incarcerated in the local county jail until December 16,
    2003. On cross-examination, Ricardo Romero had been able
    to pin down Suarez to a November 2003 date for the
    Badger Road drug delivery that Suarez claimed to have
    witnessed between Raul and Ricardo Romero. Ricardo
    Romero argued to the jury that Suarez’s testimony
    was impossible because he was in jail in November 2003
    and therefore could not have participated in any drug
    transactions at the Badger Road apartment building
    parking lot. Without Suarez’s testimony, Ricardo Romero
    postulated there was no evidence demonstrating that he
    knew what was in the cookie tin, had any intent to distrib-
    ute drugs or knew about Raul Romero’s drug dealing
    activities.
    The government also introduced evidence to establish
    that the cookie tin contained both powder cocaine and
    cocaine base. The officers who arrested Ricardo Romero
    testified that they reached their conclusions about the
    drugs they observed in the cookie tin based on their
    training and experience. A chemist from the Wisconsin
    Department of Justice Crime Laboratory also testified
    as to the testing that he performed on the seized drugs.
    The chemist stated that it was his opinion that the seized
    drugs were both powder cocaine and cocaine base com-
    monly referred to as crack cocaine.
    Nos. 05-3294 & 05-3681                                   9
    After the jury verdicts, Ricardo Romero filed a motion
    for judgment of acquittal pursuant to Rule 29(c) of the
    Federal Rules of Criminal Procedure. He argued there
    was no evidence proving his knowledge as to the existence
    of drugs in the cookie tin. The district court disagreed
    holding that there was sufficient evidence for the jury to
    have inferred that he knew that he was transporting
    drugs in the cookie tin. The district court also noted
    that the jury could have credited Suarez with being
    confused about the date that he witnessed the drug
    delivery between Ricardo and Raul Romero as Suarez was
    uncertain about the date that it had occurred. In rejecting
    Ricardo Romero’s motion, the district court commented, “In
    light of the evidence, what rational jury would believe
    that [Ricardo Romero] thought that the tin contained
    chocolate chip cookies?” R. 237 at 3.
    At sentencing, the district court determined that the
    cocaine base in the cookie tin was crack cocaine. Applying
    the November 2004 Guidelines, the district court calcu-
    lated Ricardo Romero’s base offense level at 26. U.S.S.G.
    § 2D1.1. The offense level was enhanced two levels for use
    of a minor, U.S.S.G. § 3B1.4, and an additional two level
    enhancement for obstruction of justice, U.S.S.G. § 3C1.1,
    for a total offense level of 30. Ricardo Romero had a
    criminal history of V and his corresponding Sentencing
    Guidelines Range was 151-188 months. The district court,
    after considering the factors set forth in 
    18 U.S.C. § 3553
    (a), imposed a sentence of 151 months’ imprison-
    ment.
    II. ANALYSIS
    A. Raul Romero
    On appeal, Raul Romero argues that the district court
    erred when it found that he was responsible for 2.5
    10                                 Nos. 05-3294 & 05-3681
    kilograms of cocaine and ineligible for a three level
    reduction for acceptance of responsibility. Specifically, he
    argues that the district court erred by including in the
    2.5 kilogram cocaine amount: (1) 1000 grams of cocaine
    located in Anthony Romero’s Kennedy Heights apart-
    ment, and (2) 850.5 grams of cocaine attributed to him
    from Turner’s testimony. Raul Romero concludes that
    he is responsible for at least 500 grams but less than
    2 kilograms of cocaine. He argues that his total offense
    level should only be 25, and with his criminal history
    category of III, his proposed advisory Sentencing Guide-
    lines range is 70-87 months instead of the 121-151 months
    range calculated by the district court.
    1. Relevant Conduct
    Although Booker has transformed the Guidelines from
    binding to advisory, the “district court remains oblig[ated]
    to consult the Guidelines.” United States v. Garner, 
    454 F.3d 743
    , 747 (7th Cir. 2006) (citing United States v.
    Booker, 
    543 U.S. 220
     (2005); United States v. Laufle, 
    433 F.3d 981
    , 987 (7th Cir. 2006)). This obligation requires the
    district court to have “a correct understanding of [the
    Guidelines’] application to the defendant’s conduct.”
    United States v. Avila, 
    465 F.3d 796
     (7th Cir. 2006).
    Consequently at sentencing, the “district [court] must
    resolve [factual disputes], determine relevant conduct by
    a preponderance of the evidence, and apply the appropriate
    sentenc[ing] enhancements in order to compute the
    advisory [G]uidelines Sentenc[ing] range.” United States
    v. Robinson, 
    435 F.3d 699
    , 701 (7th Cir. 2006) (citing FED.
    R. CRIM. P. 32 (i)(3)(B); U.S.S.G. § 6A1.3(b); United States
    v. Dean, 
    414 F.3d 725
    , 727 (7th Cir. 2005)).
    “The [district] court’s sentenc[ing] determinations [as to
    factual disputes] must be based on reliable evidence, not
    speculation or unfounded allegations.” United States v.
    Nos. 05-3294 & 05-3681                                    11
    Noble, 
    246 F.3d 946
    , 951 (7th Cir. 2001) (citing United
    States v. Pigee, 
    197 F.3d 879
    , 889 (7th Cir. 1999); United
    States v. Howard, 
    80 F.3d 1194
    , 1204 (7th Cir. 1996)). The
    defendant’s “due process right to be sentenced on the
    basis of accurate information . . . is generally satisfied
    when the facts in question are found by a preponderance
    of the evidence using information that has a sufficient
    indicia of reliability to support its probable accuracy.”
    United States v. Lister, 
    432 F.3d 754
    , 762 (7th Cir. 2005)
    (quoting United States v. Townsend, 
    73 F.3d 747
    , 751-52
    (7th Cir. 1996); United States v. Salinas, 
    62 F.3d 855
    , 859
    (7th Cir. 1995); United States v. Ewers, 
    54 F.3d 419
    , 421
    (7th Cir. 1995) (internal quotations and citations omitted)).
    “The [G]uidelines instruct district courts to calculate
    sentences based on types and quantities of drugs not
    specified in the counts of conviction but that were ‘part
    of the same course of conduct or common scheme or plan’
    as the convicted offenses.” United States v. Arroyo, 
    406 F.3d 881
    , 888-89 (7th Cir. 2005) (quoting U.S.S.G.
    § 1B1.3(a)(2); United States v. Bacallao, 
    149 F.3d 717
    , 719
    (7th Cir. 1998)). “Two or more offenses are part of a
    common scheme or plan when they are substantially
    connected to each other by at least one common factor,
    such as common victims, common accomplices, common
    purpose, or similar modus operandi.” United States v.
    Sumner, 
    265 F.3d 532
    , 540 (7th Cir. 2001) (quoting
    U.S.S.G. § 1B1.3(a)(2), app. n.9; United States v. Acosta, 
    85 F.3d 275
    , 281 (7th Cir. 1996)). In determining relevant
    conduct, “the district court is entitled to estimate drug
    quantity using testimony about the frequency of dealing
    and the amount dealt over a specified period of time.”
    Noble, 
    246 F.3d at
    952 (citing United States v. Durham,
    
    211 F.3d 437
    , 444 (7th Cir. 2000)). The district court is also
    entitled to credit testimony that it finds reliable even when
    that testimony is provided by an “admitted liar, convicted
    felon, or large scale drug-dealing, paid government infor-
    12                                 Nos. 05-3294 & 05-3681
    mant.” United States v. Blalock, 
    321 F.3d 686
    , 690 (7th
    Cir. 2003) (quoting United States v. Partee, 
    301 F.3d 576
    ,
    579 (7th Cir. 2002)).
    “Generally, a court is entitled to rely on the PSR in rul-
    ing on factual issues in the sentencing context so long
    as the PSR is based upon sufficiently reliable informa-
    tion.” United States v. Willis, 
    300 F.3d 803
    , 807 (7th Cir.
    2002) (citing United States v. Taylor, 
    72 F.3d 533
    , 547 (7th
    Cir. 1995)). “When the [district] court relies on such
    information in sentencing a defendant, the defendant bears
    the burden of showing that the [PSR] is inaccurate or
    unreliable.” United States v. Salinas, 
    365 F.3d 582
    , 587
    (7th Cir. 2004) (citing Taylor, 
    72 F.3d at 547
    ; United States
    v. Mustread, 
    42 F.3d 1097
    , 1101-02 (7th Cir. 1994)). The
    “defendant cannot show that a PSR is inaccurate by
    simply denying the PSR’s truth. Instead, he must produce
    some evidence that calls the reliability or correctness of
    the alleged facts into question.” United States v. Jones, 
    209 F.3d 991
    , 996 (7th Cir. 2000) (quoting Mustread, 
    42 F.3d at 1102
    ; United States v. Isirov, 
    986 F.2d 183
    , 186 (7th Cir.
    1993) (internal quotations omitted)).
    “We review the district court’s application of the Guide-
    lines de novo and its factual determinations for clear
    error.” United States v. Warren, 
    454 F.3d 752
    , 762 (7th Cir.
    2006) (citing United States v. Davis, 
    442 F.3d 1003
    , 1008-
    09 (7th Cir. 2006)). “A district court’s finding as to drug
    quantity for sentencing purposes is reviewed for clear
    error.” United States v. Smith,

    tant to disturb [a district court’s] credibility determina-
    tions absent a compelling reason.” United States v. Noble,
    
    246 F.3d 946
    , 951 (7th Cir. 2001).
    The disputed 1000 grams of cocaine relates to a Janu-
    ary 16, 2004 drug sale between Raul Romero and cooperat-
    ing witness Ticey. Raul Romero and Ticey arranged the
    sale, but Raul Romero directed Ticey to pick up the drugs
    at Anthony Romero’s Kennedy Heights apartment. Ticey
    was met by Suarez who provided the drugs to Ticey from
    a drug stash located inside Anthony Romero’s Kennedy
    Heights apartment. While in Anthony Romero’s apart-
    ment, Ticey also witnessed 1000 grams of cocaine packaged
    in 40 one-ounce bags. Ticey then called Raul Romero to
    confirm that he had received the drugs and arranged
    for payment. The district court determined that Raul
    Romero was selling drugs out of a stash located in Anthony
    Romero’s Kennedy Heights apartment and therefore Raul
    Romero was responsible for the 1000 grams of cocaine
    witnessed by Ticey in Anthony Romero’s apartment.
    Raul Romero counters that he was merely referring Ticey
    to Anthony Romero and that there was no connection
    between himself and Anthony Romero. He points to
    application note 6 to Guidelines § 1B1.3(a)(2) that dis-
    cusses the factual situation of two street level drug dealers
    who have a common source of drugs but otherwise have
    no connection. The comment states that the two street
    level drug dealers are not responsible for the conduct of
    the other dealer, despite having the same supplier.
    We find no reason to disturb the district court’s finding
    that Raul Romero is responsible for the 1000 grams of
    cocaine in Anthony Romero’s Kennedy Height’s apartment.
    The drug sale to Ticey and the offense conduct of the
    sale to the undercover officer share the common factors of
    similar modus operandi and common purpose. See United
    14                                 Nos. 05-3294 & 05-3681
    States v. Sumner, 
    265 F.3d 532
    , 540 (7th Cir. 2001) (citing
    U.S.S.G. § 1B1.3(a)(2), app. n.9; United States v. Acosta, 
    85 F.3d 275
    , 281 (7th Cir. 1996)). In both situations, Raul
    Romero made a drug sale and then sent the customer
    to pick up the drugs from the Kennedy Heights apart-
    ment. The drugs were delivered to the customer by a third
    party who had received instructions from Raul Romero. In
    both situations, the customer discussed potential future
    transactions with Raul Romero’s representative who, at
    the time, was acting on behalf of Raul Romero. Both
    transactions also had the common purpose of distribut-
    ing drugs on behalf of the Romero organization.
    We are also unconvinced by Raul Romero’s argument
    that he and Anthony Romero were merely two “street
    level” dealers who were sharing a common stash of drugs
    but otherwise were not working together. The district
    court heard testimony at the sentencing hearing from the
    DEA agent as to the significant number of wiretaps,
    undercover buys and other observations made by the
    government during its investigation of the Romero or-
    ganization. This evidence demonstrated the extent of the
    Romero organization’s drug dealing activities and Raul’s
    participation in those activities. This evidence is also
    extensively set forth in the PSR and Raul Romero has
    done nothing to rebut this evidence.
    Raul Romero also disputes 850.5 grams included in his
    offense level calculation. This amount comes from Turner’s
    testimony. Turner testified before a grand jury that he
    purchased on average three ounces of cocaine from Raul
    Romero per week over a five month basis. He also testified
    at Ricardo Romero’s trial that he purchased cocaine from
    Raul Romero on April 30, 2004. However, after his grand
    jury testimony, but before testifying at Ricardo Romero’s
    trial, Turner wrote a note to Raul Romero’s counsel stat-
    ing that he had lied to investigators and that Raul Romero
    had never sold him drugs. At sentencing, the district court
    Nos. 05-3294 & 05-3681                                    15
    credited Turner’s sworn testimony over Turner’s unsworn
    note and found Raul Romero responsible for the 850.5
    grams. The district court also found that Turner’s testi-
    mony of Raul Romero’s drug dealing activities were
    corroborated by the testimony of the DEA agent. We see
    no reason to overturn the district court’s decision on
    crediting Turner’s sworn testimony because “we are
    reluctant to disturb a [district court’s] credibility deter-
    minations absent a compelling reason.” United States v.
    Noble, 
    246 F.3d 946
    , 951 (7th Cir. 2001). Raul Romero
    provides us no compelling reason to disregard the dis-
    trict court’s decision on this issue.
    2. Acceptance of Responsibility
    The district court properly denied Raul Romero a
    reduction for acceptance of responsibility pursuant to
    Guidelines § 3E1.1 because Raul Romero frivolously
    contested his relevant conduct at the sentencing hearing.
    Although a defendant’s entry of a guilty plea may demon-
    strate that he has accepted responsibility for his crim-
    inal acts, a guilty plea does not qualify the defendant for
    an acceptance of responsibility reduction as a matter of
    right. United States v. Leahy, 
    464 F.3d 773
    , 791 (7th Cir.
    2006) (citing United States v. Bothum, 
    424 F.3d 582
    , 586
    (7th Cir. 2005); United States v. Willis, 
    300 F.3d 803
    , 807
    (7th Cir. 2002)). “A defendant who ‘falsely denies, or
    frivolously contests, relevant conduct that the court
    determines to be true has acted in a manner inconsistent
    with acceptance of responsibility.’ ” United States v. Sharp,
    
    436 F.3d 730
    , 735 (7th Cir. 2006) (citing U.S.S.G. § 3E1.1
    cmt. n.1(a)).
    Not only was there significant evidence to support the
    2.5 kilograms of cocaine, but as the government properly
    noted at sentencing, the relevant conduct set forth in
    the PSR under-reported the extent of Raul Romero’s
    16                                 Nos. 05-3294 & 05-3681
    criminal activities. We are unsure as to why the govern-
    ment acquiesced to the under-reporting of Raul Romero’s
    relevant conduct in the PSR, but we will move beyond
    that question as the government did not object at sentenc-
    ing and has not cross-appealed. Regardless, there was
    more than sufficient evidence to substantiate the 2.5
    kilograms of cocaine based on the information set forth
    in the PSR and considered by the district court at the
    sentencing hearing. The district court’s conclusion that
    Raul Romero raised a frivolous argument on the relevant
    conduct issue was not a clear error and therefore we see
    no reason to disturb the district court’s decision.
    In closing, we note that Raul Romero does not otherwise
    challenge his Guidelines calculation. The district court
    understood the advisory nature of the Guidelines, properly
    calculated the Guidelines range and considered the
    sentencing factors set forth in 
    18 U.S.C. § 3553
    (a). Raul
    Romero’s sentence of 130 months’ imprisonment is
    within the Guidelines range of 121 to 151 months’ impris-
    onment and is therefore entitled to a rebuttable pre-
    sumption of reasonableness. See United States v. Mykytiuk,
    
    415 F.3d 606
    , 608 (7th Cir. 2005). We see no reason to
    find Raul Romero’s sentence unreasonable and therefore
    it shall be affirmed.
    B. Ricardo Romero
    1. Sixth Amendment Cross-Examination Claim
    On appeal, Ricardo Romero argues that the district
    court erred by refusing his attempt to cross-examine
    Almeida on her prior inconsistent statement from the
    state court proceeding. “The Sixth Amendment right of
    confrontation requires that a defendant be given an
    opportunity for effective cross-examination.” United States
    v. Smith, 
    454 F.3d 707
    , 714 (7th Cir. 2006) (citing Pennsyl-
    Nos. 05-3294 & 05-3681                                    17
    vania v. Ritchie, 
    480 U.S. 39
    , 51 (1987); Delaware v. Van
    Arsdall, 
    475 U.S. 673
    , 678 (1986)). “The right to cross-
    examine is not unlimited; the Confrontation Clause
    guarantees only effective cross-examination, not cross-
    examination of any type sought by the defendant.” United
    States v. Williamson, 
    202 F.3d 974
    , 977 (7th Cir. 2000)
    (citing Delaware v. Fensterer, 
    474 U.S. 15
    , 20 (1985)).
    “[T]rial courts have wide latitude ‘to impose reasonable
    limits on . . . cross-examination based on concerns about,
    among other things, harassment, prejudice, confusion of
    the issues, the witness’s safety, or interrogation that is
    repetitive or only marginally relevant.’ ” United States v.
    McGee, 
    408 F.3d 966
    , 975 (7th Cir. 2005) (quoting Van
    Arsdall, 
    475 U.S. at 679
    ).
    Our standard of review is determined through our
    evaluation of whether the alleged error implicates “core
    values of the [Sixth Amendment] confrontation right” or
    instead merely implicates “peripheral concerns.” United
    States v. Degraffenried, 
    339 F.3d 576
    , 581 (7th Cir. 2003)
    (citing United States v. Saunders, 
    973 F.2d 1354
    , 1358 (7th
    Cir. 1992)). An alleged error implicates a core value
    when the defendant was unable to cross-examine a wit-
    ness at all on an issue protected by the Sixth Amend-
    ment while a peripheral concern involves the extent of
    the defendant’s ability to cross-examine on an issue. See,
    e.g., United States v. Nelson, 
    39 F.3d 705
    , 708 (7th Cir.
    1994) (“[O]nce this core function is satisfied by allowing
    cross-examination to expose a motive to lie, it is of periph-
    eral concern to the Sixth Amendment how much opportu-
    nity defense counsel gets to hammer that point home to
    the jury.”). “When reviewing the adequacy of a cross-
    examination, the question is whether the jury had suffi-
    cient information to make a discriminating appraisal of
    the witness’s motives and bias.” United States v. McLee,
    
    436 F.3d 751
    , 762 (7th Cir. 2006) (quoting Nelson, 
    39 F.3d at 708
    ; United States v. Robinson, 
    832 F.2d 366
    , 373 (7th
    18                                Nos. 05-3294 & 05-3681
    Cir. 1987); United States v. DeGudino, 
    722 F.2d 1351
    , 1354
    (7th Cir. 1983)). We review claimed errors implicating the
    core value of the Sixth Amendment de novo while we
    review peripheral concerns for abuse of discretion. Smith,
    
    454 F.3d at
    714 (citing Nelson, 
    39 F.3d at 708
    ).
    Ricardo Romero’s theory both at trial and on appeal is
    that Almeida is a “ ‘Yes [Wo]man’ for the prosecution,” a
    person who is willing to testify in a manner to satisfy
    the government, even if that requires her to lie. Ricardo
    Romero Br. at 30. Ricardo Romero attempted to demon-
    strate Almeida’s alleged bias through extensive cross-
    examination of her at trial. He brought out the fact that
    she had a scholarship to the University of Wisconsin-
    Madison at the time of her arrest on April 30, 2004, and
    that she was worried about the potential impact of her
    arrest on her future college plans when she was inter-
    viewed by the police. Cross-examination also brought out
    that her relationship with Ricardo Romero ended after
    the arrest. He was able to examine her regarding her
    concerns about being prosecuted after the arrest but that
    she was not prosecuted after she agreed to cooperate with
    the government. Ricardo Romero also cross-examined
    Almeida about prior inconsistent statements that she
    had made to the police during the various interviews
    conducted after the April 30, 2004 arrest. He was able to
    draw out inconsistencies in her statements to the police
    about when Almeida saw him in possession of the cookie
    tin. This allowed Ricardo Romero to imply that Almeida
    had changed her story in favor of the government once
    she began cooperating with the government.
    However, the district court prevented Ricardo Romero
    from cross-examining Almeida on an alleged inconsistent
    statement that she made while testifying in a state
    court proceeding. The state court proceeding involved a
    battery charge against Ricardo Romero. The police ques-
    tioned Almeida about both the battery and the cookie tin
    during her interviews. Ricardo Romero argues that he
    Nos. 05-3294 & 05-3681                                   19
    should have been allowed to cross-examine Almeida on
    the inconsistent statement between Almeida’s trial testi-
    mony in the battery case and her original statements to
    the police on the battery issue. The government objected
    to this line of impeachment and the district court agreed
    with the government holding that the battery case was
    too attenuated from the present drug case to be dis-
    cussed and would also unduly confuse the jury.
    We conclude that the district court’s exclusion of cross-
    examination on the Almeida’s prior statement in the
    state court battery case implicated a peripheral concern
    and therefore we review the district court’s decision
    under the abuse of discretion standard. In reviewing the
    record on this issue, we hold that the district court did not
    abuse its discretion by preventing cross-examination on
    Almeida’s inconsistent statements in the state battery
    case. Ricardo Romero was given ample opportunity to
    cross-examine Almeida on her potential biases and rea-
    sons for potentially not telling the truth while testifying
    at trial. He was also able to show prior inconsistent
    statements between her police interviews and her in-
    court testimony at trial. The district court allowed
    Ricardo Romero a substantial opportunity to pursue his
    theory of “Almeida as the ‘Yes Woman’ ” for the prosecu-
    tion through several areas of impeachment. The district
    court acted within the scope of her discretion by pro-
    hibiting cross-examination on the battery case as that
    cross-examination was only marginally relevant and
    would have confused the issues before the jury. United
    States v. McGee, 
    408 F.3d 966
    , 975 (7th Cir. 2005) (citing
    Delaware v. Van Arsdall, 
    475 U.S. 673
    , 679 (1986)).
    2. Sufficiency of the Evidence
    Ricardo Romero argues that the district court erred
    when she denied his motion for judgment of acquittal
    20                                 Nos. 05-3294 & 05-3681
    based on the sufficiency of the evidence supporting the
    conviction. He argues that there was no evidence estab-
    lishing that he had any knowledge that there were drugs
    in the cookie tin. “We review the district court’s denial of
    a motion for judgment of acquittal de novo.” United States
    v. James, 
    464 F.3d 699
    , 705 (7th Cir. 2006) (citing United
    States v. Jones, 
    371 F.3d 363
    , 365 (7th Cir. 2004); United
    States v. O’Hara, 
    301 F.3d 563
    , 569 (7th Cir. 2002)). “A
    party challenging the sufficiency of the evidence support-
    ing a jury conviction faces a steep uphill battle.” United
    States v. Moore, 
    425 F.3d 1061
    , 1072 (7th Cir. 2005)
    (quoting United States v. Graham, 
    315 F.3d 777
    , 781 (7th
    Cir. 2003)). “We must determine ‘whether, after viewing
    the evidence in the light most favorable to the prosecu-
    tion, any rational trier of fact could have found the essen-
    tial elements of the crime beyond a reasonable doubt.’ ”
    United States v. Haddad, 
    462 F.3d 783
    , 791 (7th Cir. 2006)
    (quoting Jackson v. Virginia, 
    443 U.S. 307
    , 319 (1979)).
    There is sufficient evidence in the record to support
    the jury’s finding that Ricardo Romero knew that there
    were drugs in the cookie tin and therefore we must uphold
    his conviction. Most notable is Ricardo Romero’s change
    in deciding who should hold the cookie tin upon arriving
    outside the Troy Drive apartment. Before arriving outside
    the apartment, he personally held the cookie tin. However,
    once they arrived, he gave the tin to Almeida to hold for
    the walk into the apartment building but then immediately
    “grabbed” the cookie tin from her purse once in the apart-
    ment building. Tr. at 114-15, June 20, 2005. Almeida was
    also given the cookie tin to hold upon leaving the apart-
    ment. The jury could have also considered Suarez’s
    testimony that Ricardo Romero had previously acted as
    a drug courier for Raul Romero in determining that
    Ricardo Romero was knowingly acting as a drug courier for
    Raul Romero on April 30, 2004.
    Nos. 05-3294 & 05-3681                                    21
    Much of Ricardo Romero’s argument as to Almeida’s
    testimony is nothing more than an attempt to reargue the
    evidence. However, “[v]iewing the evidence in the light
    most favorable to the prosecution means that on review
    we will not—despite defendants’ frequent requests to do
    so—‘weigh the evidence or second guess the jury’s credibil-
    ity determinations.’ ” United States v. Stevens, 
    453 F.3d 963
    , 965 (7th Cir. 2006) (quoting United States v. Gardner,
    
    238 F.3d 878
    , 879 (7th Cir. 2001)). The jury rejected
    Ricardo Romero’s impeachment efforts of Almeida on the
    issue of his knowledge and found her version of the
    events credible.
    We must also note that Ricardo Romero’s argument
    misstates Almeida’s role in this case. He argues that the
    evidence in the case demonstrated that she had no knowl-
    edge that there were drugs in the cookie tin. He then
    argues that the he was in the same position as Almeida
    and therefore concludes that if the evidence demonstrated
    that she lacked knowledge then he too lacked knowledge
    of drugs in the cookie tin. This argument is incorrect
    because only Ricardo Romero’s knowledge was at issue
    at trial, Almeida’s knowledge was not an issue before
    the jury. The fact that the prosecution decided not to
    charge Almeida is irrelevant on the issue of her knowledge
    as the prosecutor, acting in concert with the grand jury,
    has significant discretion in deciding whether or not to
    bring a charge. See United States v. O’Neill, 
    437 F.3d 654
    ,
    660 (7th Cir. 2006) (Posner, J., concurring) (citing Wayte v.
    United States, 
    470 U.S. 598
    , 607 (1985); United States v.
    Giannattasio, 
    979 F.2d 98
    , 100 (7th Cir. 1992) (“The
    exercise of prosecutorial discretion is a prerogative of the
    executive branch of government.”)).
    Ricardo Romero’s final argument is that Suarez’s
    testimony about the Fall 2003 drug delivery to the Badger
    Road apartment building parking lot must be rejected as
    incredible as a matter of law. Ricardo Romero was able to
    22                                Nos. 05-3294 & 05-3681
    introduce evidence that he was incarcerated at the local
    county jail until December 16, 2003 and therefore
    could not have participated in the alleged drug delivery.
    “We will not upset the jury’s credibility determinations
    unless ‘exceptional circumstances’ exist; that is, it was
    ‘physically impossible for the witness to observe that
    which he claims occurred, or impossible under the laws of
    nature for the occurrence to have taken place at all.’ ”
    United States v. Johnson, 
    437 F.3d 665
    , 675 (7th Cir. 2006)
    (quoting United States v. Smith, 
    393 F.3d 717
    , 719 (7th
    Cir. 2004)). Suarez testified on direct examination that he
    witnessed the drug delivery between Ricardo and Raul
    Romero on Badger Road sometime in the winter time. He
    also said that he did not know an exact date. On cross
    examination, Ricardo Romero tried to pin Suarez down on
    a date. Suarez was unable at first to give an exact date
    saying that the delivery occurred in the winter time and
    that it was cold outside. He also said that he could not
    remember if it was before or after Thanksgiving as he
    did not pay attention to that holiday. However, Ricardo
    Romero was eventually able to get Suarez to say Novem-
    ber for the date.
    A rational jury could have credited Suarez as being
    unsure about the exact date of the Badger Road drug
    delivery. The jury could have also believed that Suarez
    confused the date that he witnessed the drug delivery as
    his original answer focused on the fact that it was winter
    time and cold outside. Furthermore, even if Suarez’s
    testimony is rejected, we find that there was still suf-
    ficient evidence for a rational jury to have found that
    Ricardo Romero had knowledge that there were drugs in
    the cookie tin on April 30, 2004.
    3. Sentencing
    Ricardo Romero argues that the district court com-
    mitted clear error when she found at sentencing that the
    Nos. 05-3294 & 05-3681                                   23
    cocaine base seized in the cookie tin was crack cocaine. We
    have previously held that the enhanced penalties for
    cocaine base apply to the specific subset of cocaine base
    know as “crack cocaine.” See United States v. Edwards, 
    397 F.3d 570
    , 571-72 (7th Cir. 2005). “ ‘Crack’ [cocaine] is the
    street name for another form of freebase cocaine, produced
    by mixing cocaine hydrochloride with baking soda and
    water, boiling the mixture until only a solid substance
    is left, and allowing it to dry, resulting in a rocklike
    substance.” 
    Id. at 574
    . However, “we have repeatedly held
    that the government can prove a substance is crack
    [cocaine] by offering testimony from people familiar with
    the drug.” United States v. Anderson, 
    450 F.3d 294
    , 301
    (7th Cir. 2006). Individuals familiar with crack cocaine
    and therefore able to identify it include veteran narcotics
    agents and forensic chemists. United States v. Linton, 
    235 F.3d 328
    , 329-30 (7th Cir. 2000) (citing United States v.
    Abdul, 
    122 F.3d 477
     (7th Cir. 1997)). The district court
    properly credited the testimony of the narcotics officers
    and government chemist that the cocaine base seized
    from Ricardo Romero was crack cocaine and we see no
    reason to find that this was a clear error.
    Finally, Ricardo Romero argues that his sentence
    should be overturned because the imposition of the 100:1
    crack cocaine to powder cocaine ratio unreasonably
    creates an unwarranted sentencing disparity. However,
    “a district judge is required to abide by the [100:1] crack
    cocaine to cocaine powder ratio when applying the Sen-
    tencing Guidelines to a defendant’s conduct.” United States
    v. Hankton, 
    463 F.3d 626
    , 629 (7th Cir. 2006) (quoting
    United States v. Miller, 
    450 F.3d 270
    , 275 (7th Cir. 2006)).
    Ricardo Romero provides no valid argument for us to find
    that his sentence was unreasonable. The district
    court understood the advisory nature of the Guidelines,
    properly calculated the Guidelines range and considered
    the sentencing factors set forth in 
    18 U.S.C. § 3553
    (a).
    24                               Nos. 05-3294 & 05-3681
    Ricardo Romero’s sentence of 151 months’ imprisonment
    is within the Guidelines range of 151 to 188 months’
    imprisonment and is therefore entitled to a rebuttable
    presumption of reasonableness. See United States v.
    Mykytiuk, 
    415 F.3d 606
    , 608 (7th Cir. 2005). We see no
    reason to find Ricardo Romero’s sentence unreasonable
    and therefore it shall be affirmed.
    III. CONCLUSION
    Raul Romero’s sentence and Ricardo Romero’s convic-
    tion and sentence are AFFIRMED.
