One other thought:
If we assume the final gear is also the final multiplier (is that logical? Math-types chime in) then the difference in effective gearing between the 7AT and 6MT is less when both are dynoed in 4th than when dynoed in 5th, given the higher numerical final gearing of the 6MT.
Thus I
think everyone should actually just dyno in 4th, both 7AT and 6MT, in order to make comparisons more comparable.
Yes? No?
