Terrific effort!

I used to do this for hours at a time, comparing various cars, plus same car with different gearing, etc, etc. I called the results the "Dunderbex Numbers", which meant nothing in particular but sounded vaguely technical.

The one thing I found problematical (as you do ) is that I could never effectively show graphical results of automatic cars with any accuracy. There just isn't enough published data generally available in regard to torque converter stall points, slip rates and actual torque multiplication to come up with anything meaningful.
