In addition, if the sampling technique is appropriate, the results obtained therefrom in determining estimated future redemptions will be considered accurate and reliable if the evaluation of such results is consistent with sound statistical principles. Ordinarily, samplings and recomputations of the estimated future redemptions will be required annually. However, the facts and circumstances in a particular case may justify such a recomputation being taken less frequently than annually. In addition, the Commissioner may prescribe procedures indicating that samples made to update the results of a sample of stamps redeemed in a prior year need not be the same size as the sample of such prior year.
