You can take the bottom weight break to figure the minimum weight, with driver, across the scales (7.5 for AA, 8 for A). So 8 x 390 + 170 = 3,290. AA weight is 7.5 x 390 + 170 = 3,095

What happens when the DP gets enough horsepower to be in AA only?
Normally,when you are substantially over the minimun weight for your class,you drop down.If you can't drop down from AA,you would be at a disadvantage racing another AA if you weren't at the minimum weight.
