Hello everyone. I have a question, I will redesign the joystick and thought was put into one of the sticks a dial axis as the link:

And use the axis as buttons. Mmjoy recognizes me well, I assign axis 1 and 2 and in the section axis button to select these axes. My question is on the percentage to be put?.
