If the largest HP reduction annually is 2.25% based on a current year run of no quicker than -0.101 to -0.165 how does the 1962 Pontiac 421/ 405 go from 385 HP to 360 HP. 2.25 % of 385 is, after rounding, is 9 HP not 25 HP. It looks like the 227/ 260 Ford received more than 2.25% reduction. After rounding the power should be 254 not the 234.

I would bet that after the first of the year the numbers will be more accurate.
