Deadband: This is the easiest of all. As little as possible, as much as neccessary. Start with the slider all at the bottom. Watch those blue boxes with the lines to the right. The lines should be all smooth and straight when you dont move your Joystick. You even should be able to gently wiggle your stick in its center position with out them reacting. If you see any spiking there, add a little deadband (millimeter by millimeter) untill they stay smooth.
Damping: This adds an overall 'sluggishness' to your JS inputs, kind of like a small temporal delay added to the reaction to stick input. Depending, if you have a rather light hand on your stick youll probably want this to be as low as possible (i got mine all at the bottom). If you feel your input is too touchy overall, raise this slider (try small adjustments at a time).
