This is an appeal from the judgment of sentence of the Court of Common Pleas of Philadelphia County. Appellant was charged with knowing or intentional possession of a controlled substance and manufacture, delivery, or possession of a controlled substance with intent to manufacture or deliver. He was adjudged guilty of both charges after a non-jury trial, and was sentenced to a term of incarceration of not less than two (2) or more than eight (8) years. Appellant’s motion for reduction of sentence was denied. He then filed the instant timely appeal.
The charges against appellant arose out of an occurrence on May 17, 1988, in which appellant was observed handing a plastic bag filled with packets to another individual. After appellant’s arrest, the bag was recovered and two of the packets were analyzed. Those two packets were found to contain 229 and 230 milligrams of cocaine respectively. The lower court extrapolated the weight of the entire bag of fifty packets to be approximately ten (10) grams based on the measured weights of the two packets. On appeal, appellant raises the following issues: (1) whether the lower court, in determining the appropriate offense gravity score under the sentencing guidelines for drug offenses, improperly extrapolated the weight of the entire bag based upon the weights of the measured individual packets; (2) whether the lower court abused its discretion in sentencing appellant “by overemphasizing as a factor that [appellant] proceeded to trial rather than submitting to a guilty plea”; and (3) whether the lower court adequately considered “the positive factors in [appellant’s] behalf” when sentencing.
Sentencing is a matter vested in the sound discretion of the sentencing judge, and a sentence will not be disturbed on appeal absent a manifest abuse of that discretion.
Commonwealth v. Fries,
Appellant has included in his appellate brief a statement of reasons relied upon for allowance of appeal, pursuant to Pa.R.A.P., Rule 2119(f). Thus, he has complied with the procedural requirements for a challenge to the discretionary aspects of sentence.
Commonwealth v. Tuladziecki,
The determination of whether a particular issue constitutes a substantial question must be evaluated on a case by case basis.
Commonwealth v. Losch,
We have reviewed appellant’s brief including his Rule 2119(f) statement and conclude that appellant has stated a substantial question only as to the first issue raised on appeal,
i.e.,
whether the lower court applied the wrong offense gravity score in computing appellant’s sentence under the drug offense guidelines as a result of the court’s allegedly improper extrapolation of the weight of the entire bag of cocaine packets. Appellant has not stated a substantial question with regard to the remaining issues on appeal because each of those issues challenges the discretion of the court in “overemphasizing” or “failing to adequately consider” certain factors relevant to the sentencing determination, and appellant’s Rule 2119(f) statement contains no factual

averments which would suggest that the sentencing scheme as a whole has been compromised.
See Commonwealth v. Williams,
Turning to the merits of that issue, we note that in imposing sentence, the sentencing court is to follow the general principle that the sentence imposed should be the minimum sentence consistent with the protection of the public, the gravity of the offense, and the rehabilitative needs of the defendant. 42 Pa.C.S.A. § 9721(b);
Commonwealth v. Edward,
Although the sentencing guidelines specify definitive ranges of minimum sentences, the adoption of the guidelines was not intended to preclude judicial discretion.
Commonwealth v. Frazier,
In the case sub judice, the lower court considered the sentencing guidelines relevant to offenses arising from violations of the Controlled Substance, Drug, Device and Cosmetic Act, 35 P.S. § 780-113 and found that appellant had committed an offense of the level “E” with respect to the offense gravity score. An offense gravity score of “E” under the guidelines for drug offenses is assigned when the offense involves a violation of 35 P.S. § 780-113(a)(12), (a)(14), or (a)(30) and a quantity of PCP, cocaine, or methamphetamine of two (2) grams to one hundred (100) grams. With an offense gravity score of “E” and a prior record score of zero (0), the standard range of minimum sentence under the guidelines is fifteen (15) to twenty-seven (27) months. An offense gravity score of “F” for the same *559 offenses would be appropriate if the amount of drugs involved was less than two (2) grams. With an “F” offense gravity score and a prior record score of zero (0), the standard range of minimum sentence would be from six (6) to fifteen (15) months. This is in fact appellant’s contention on appeal, that the appropriate offense gravity score for his offenses was “F,” and that therefore a minimum sentence of two years was erroneous. The maximum sentence for the offenses of which appellant was convicted is fifteen (15) years. 35 P.S. § 780-113(f)(l). Therefore, the maximum sentence of eight (8) years assigned by the court was within the statutory limits.
In selecting an offense gravity score of “E” for appellant’s offenses, the lower court extrapolated the amount of cocaine present in the fifty packets seized by multiplying fifty times the amount of cocaine found in two representative packets field tested by a chemist. Such extrapolation yields a quantity well in excess of two grams, the minimum amount for application of the grade “E” offense gravity score. It is this extrapolation which appellant contends was an impermissible exercise of the court’s sentencing discretion. For the following reasons, we do not agree that the lower court abused its discretion in this regard.
The practice of testing representative samples of larger quantities of drugs and extrapolating therefrom the total narcotic content of illegal substances is well accepted. In Pennsylvania, this method was approved in
Commonwealth v. Gorodetsky,
The extrapolation of drug quantities was approved in the context of the sentencing phase of a criminal process in
United States v. Fuentes,
Extrapolation has also been approved as a legitimate fact-finding process in the context of determining blood alcohol content with regard to offenses arising under the Motor Vehicle Code. In
Commonwealth v. Slingerland,
*562
It is also well-established in this Commonwealth that the identity of illegal narcotic substances may be established by circumstantial evidence alone, without any chemical analysis of the seized contraband.
Commonwealth v. Stasiak,
Judgment of sentence affirmed.
