So how much is the difference between the first km/h from 0-1km/h and let's say 1499-1500km/h in the other games? Do you know any maths about it?

Edit: I tested in F-Zero X on a big loop. I drove on max speed settings at ~901km/h and another time while braking at the same time, so that my speed was only ~179km/h. Based on the time I did with 179km/h I expected the other time I did to be ~918km/h instead of 901. So the difference isn't really that huge, especially compared to F-Zero SNES, it is even the other way around, the expected 918km/h are higher than the 901km/h, while in F-Zero SNES the expected 350km/h for half the time of 175km/h are much lower than 478km/h. Maybe there is a bigger difference at lower speeds, but I don't know how to drive constant times at lower speeds.
