this could be solved by requiring a minimum cursor movement before the value changes. If you want only a small change, you need to move it beyond the trigger limit, then back again

the same idea would help with getting exactly 100 or 0 values - if moving back set the "zero" zone between 0 and about -10, or going the other way once you hit 100 you need to progress significantly past it, say to about 10, before it wraps value
