We tend to get a twitch, when trying to hold a wheel at a position that crosses from 5v - 0v. It probably could be calibrated out. We just don't set any wheels in either drive or strafe position to this position.

I would not recommend trying anything other than absolute feedback geared one to one with the wheel.
If you read the technical documents, you will find that the voltage output is not 0v to 5v. Depending on the model, I think it's roughly 0.1v to 4.9v. It's very simple to fix.
