There are so many threads with failing faders that there might be an opportunity to try a software workaround. Maybe a new "reduce noise on faders" option could be used to enable some hysteresis on actual movement up and down and limits of a single movement. It might even help to do more analysis to see if the movement is linear. For example If this is the first movement, store direction (up/down) If movement is more than NOISE THRESHOLD and less than MAXIMUM then update software fader. Set TIMEOUT for reset of movement state If TIMEOUT has not expired, check new position is in same direction. Reject if false. If new position is more than NOISE THRESHOLD and less than MAXIMUM then update software fader. I'm over simplifying this, but it could save you and users many service calls if there was a way to at least try a basic software workaround.
