So much of it comes down to how motivated the rider is that there isn't a dollar number that would have meaning.
Gains are logarithmic/exponential or similar. Asymptotic. At some point, infinity money = only half the gain of not-infinity money. Sorry....And that, of course is entertaining the idea that there is a relationship between dollars & speed. Which, if there is, then it is merely coincidental.
If you want to get faster that is one discussion. If you want more ability, that is another. To dominate, you need both.
