I know my Bridgeport does rock, but it has worn dovetail ways on it. Also, it can't be totally trusted to settle on the screw, even with no counterbalance system. If you put the encoder on the outer shaft, then you will definitely have to always make the last adjustment in the same direction, but that is pretty easy to do.
