I've thought about this some more, and maybe it works like this?
If we assume the change in Throttle Position (TP) vs Pedal Position (PP) is nearly 1:1 (linear) when the gearshift is in Drive, then possibly the change in TP vs PP is more parabolic with the shifter in 2nd or 1st? In other words, possibly TP reaches the same maximum point in the lower gears, but it does it more slowly at first?
Thinking about it, that's the way I would have designed the relationship, because there's no reason I can think of to limit the max TP.
(And I know the Drive TP vs PP doesn't have to be linear, I just used that as a base for comparison).
