Increase effect of modifier key

[muaka]

I want to increase the effect of the control stick modifier from 50% to about 35%. I tried right-clicking the modifier key and altering the range there, but it didn't do anything. I'm using build 4.0-5886. If anybody knows how to do this, I'd appreciate it a lot.
