here are some generic velocity curves for fast keyboards in case neither the standard "fast" nor the "moderately fast" is fitting you.
The curve's exponent is increased by 0.05 with each curve starting at near linear and going to a very fast keyboard.
You can use these curves as a starting point for finding your very own curve if you have a fast keyboard.
1.9 is about the same as "fast" and 1.5 about the same as "moderately fast".
