I added some explanations of how the curve works in the OP. Like OBsIV said, the best way to learn this stuff is to just try it. I remember spending HOURS with the XIM2 by myself in a private match just trying different settings, one at a time, until I understood what was happening.
At first it was very confusing, but after some time, the light bulb went off, and I learned how to make some pretty nice configs.
