Maybe I'm thinking the same thing that you guys are talking about here, but why not figure out which gears give you the most similar roll out between transmissions? Lets go hypothetical here. Lets pretend fifth gear in the mt gives you a roll out of 20 ft and 4th gear only gets you 15 ft. Then the AT gives you a roll out of 17 feet in fifth and 14 ft in fourth. It would be a much closer comparison if you used 5th gear in the MT and 4th in the AT in this scenario. Granted in order to figure out roll out you would have to know the circumference of the tire. Also if you change tire sizes it would require a recalculation. It would be awesome if you figure out a way to make this work.
Honestly though I look at dyno graphs to see what percentage they gained. The logic I apply is that if they gained 10% hp or 10% torque, then I should see something pretty close to 10% on my car regardless of what dyno or gear I use as long as I keep those two variables constant.
