OPINION
Thomas Dalton appeals the sentence arising from his conviction for credit card fraud in violation of 18 U.S.C. § 1029(a)(2) (2000). He argues that the district court acted unreasonably in imposing a 105-month sentence, an upward departure of nearly eighty-five percent from the top of the advisory guidelines range. While we decline defendant’s invitation to hold any upward departure unreasonable, the degree of departure from the advisory guidelines range requires further explanation and we therefore vacate and remand for resentencing.
I.
Defendant Thomas Dalton used other people’s credit cards to buy approximately $100,000 worth of computer programs over the Internet. He then sold the expensive software on E-Bay. On December 10, 2003, Dalton was indicted on one count of credit card fraud. The indictment charged Dalton with the knowing and intentional use of more than one unauthorized access *197 device to obtain goods, services, and cash having an aggregate value in excess of $1,000 in violation of 18 U.S.C. § 1029(a)(2).
Dalton pled guilty on March 1, 2004. On September 8, 2004, the district court sentenced him to a term of 105 months’ imprisonment, three years supervised release, restitution in the amount of $98,851.64, and a $100 special assessment under the then mandatory guidelines. Dalton appealed and this court remanded for resentencing in light of the Supreme Court’s intervening decision in

The district court in this case granted the government’s motion for upward departure on the ground that Dalton’s criminal history category inadequately reflected his actual criminal history.
See
U.S. Sentencing Guidelines Manual (“U.S.S.G.”) § 4A1.3 (2006). Because the district court properly imposed a departure sentence before considering a variance sentence,
Davenport,
To begin with, the presentence investigation report (“PSR”) in this case recommended a base offense level of six and a total offense level of sixteen. See U.S.S.G § 2B1.1(a)(2). Based on Dalton’s past criminal conduct, the PSR assigned him fifteen criminal history points, placing him in Criminal History Category VI. The advisory guidelines range for Dalton’s sentence was 46-57 months’ imprisonment.
At the first sentencing hearing, the district court adopted paragraphs 1 through 116 of the PSR as findings of fact. The court found that Dalton had twenty-three potential criminal history points that had not been included in Dalton’s criminal history count. It combined these points with the countable criminal history points, arriving at a total criminal history score well beyond the thirteen points needed to establish a criminal history category of six. Based on these criminal history findings, the district court granted the government’s motion for an upward departure and extended the table horizontally impos *198 ing a 105-month sentence. On remand, the district court again evaluated defendant’s criminal history; the court then considered the 18 U.S.C. § 3553(a) sentencing factors, determined that the appropriate guidelines range was 100 to 125 months, and reimposed the 105-month sentence.

Dalton maintains that the 105-month sentence imposed by the district court was unreasonable. The Sentencing Guidelines specify that an upward departure is warranted when “reliable information indicates that the defendant’s criminal history category substantially under-represents the seriousness of the defendant’s criminal history or the likelihood that the defendant will commit other crimes.” U.S.S.G. § 4A1.3. To determine whether a criminal history category underrepresents the seriousness of a defendant’s criminal history, a district court may consider both “[p]rior sentences not used in computing the criminal history category” and “[p]rior similar adult criminal conduct not resulting in a criminal conviction.” U.S.S.G. § 4A1.3(a)(2)(A),(E).
In light of these principles, the district court’s conclusion that “Dalton’s criminal history category of six does not adequately reflect [his] past criminal conduct or his chances of recidivism” was a reasonable one.
See United States v. Cash,
We do note that the district court’s findings of twenty-one attributable criminal history points and twenty-three potential history points are in tension with the PSR, which calculated fifteen criminal history points. On remand, the district court should explain its criminal history calculations, specifying which arrests and convictions form the basis for the additional points. But the fact remains that an upward departure on the ground that the criminal history category underrepresented Dalton’s criminal history was undeniably reasonable. As the district court explained, defendant’s forty arrests as well as his admission that he had on many occasions promptly resumed his fraudulent enterprises upon release from jail—indeed, even conducting some of those enterprises from jail—demonstrated a “continuing pattern of criminal behavior [that] reflects a high probability of recidivism.” As a result, Dalton “would pose a serious risk to the community” if the instant offense were
*199
“not adequately addressed.” Thus, the district court “reasonably concluded that a sentence above the advisory guideline range was warranted.”
Davenport,
B.
Nonetheless, even where an upward departure from Criminal History Category VI is plainly warranted, a sentencing court must depart incrementally, explaining the reasons for its departure. The Sentencing Guidelines provide that when a sentencing court “determines that the extent and nature of the defendant’s criminal history ... warrant an upward departure from Criminal History Category VI” the court “should structure the departure
by moving incrementally down the sentencing table
to the next higher offense level in Criminal History Category VI until it finds a guideline range appropriate to the case.” U.S.S.G. § 4A1.3(a)(4)(B) (emphasis added). A court, in other words, “should move to successively higher categories only upon finding that the prior category does not provide a sentence that adequately reflects the seriousness of the defendant’s criminal conduct.”

To begin with, the district court failed to employ the incremental approach dictated by § 4A1.3(a)(4)(B).
See Cash,
Here, however, the district court imposed a sentence almost twice the top of the advisory guidelines range. Whether a departure is upward or downward, “[t]he farther the [sentencing] court diverges from the advisory guideline range,” the more a reviewing court must “carefully scrutinize the reasoning offered by the district court in support of the sentence.”
United States v. Hampton,
2.
The district court also erred by extending the sentencing table beyond Criminal History Category VI on a horizontal axis. When a defendant is already in the highest criminal history category, Category VI, a sentencing court must depart on the vertical axis, “moving incrementally
down
the sentencing table to the next higher offense level.” U.S.S.G. § 4A1.3(a)(4)(B) (emphasis added);
see also United States v. Smith,
In sum, defendant’s criminal history is serious and his rate of recidivism glaring. Therefore, the district court’s decision to depart upward from Criminal History Category VI was reasonable. Because the court’s departure from the advisory guidelines range was substantial, however, and because the court failed to make incremental findings as required by the Sentencing Guidelines at § 4A1.3, a more rigorous sentencing analysis is required. We thus vacate the sentence and remand to the district court for further proceedings.
VACATED AND REMANDED.
Notes
. Defendant's contention that the district court erred by considering prior arrests misses the mark. Although section 4A1.3 provides that “a prior arrest record itself” may not form the basis for a departure, a departure may be based upon "the facts underlying [pri- or] arrests.”
United States
v.
Dixon,
. Defendant also claims that the district court erred by counting the seriousness of his offense against him twice. He argues that the court not only increased his base offense level by ten points due to the amount of loss and method used to commit the fraud, but also departed upward based on its view of the seriousness of the offense—“a matter already accounted for in the Sentencing Guideline calculation." Defendant's contention is without merit: the sentencing court's upward departure was based on the seriousness of Dalton’s past criminal histoiy, not the seriousness of his present offense.
. We note the district court's reliance on this court's suggestion in
United States v. Cash
that a sentencing court might extrapolate horizontally from Category VI. See
