-14- theoretical profit unreasonably exaggerates Mr. Paterson’s income. We disagree. Mr. Paterson has introduced no evidence of his actual profit margin or any evidence that would tend to show respondent’s method was unreasonable or incorrect.

Commissioner, 96 T.C. 858, 867 (1991), affd. 959 F.2d 16 (2d Cir. 1992).
