I think it would be so diificult to measure this acurately using current draw, but again maybe it is possible.
We have ATC using an encoder wheel on the floor. We found you can have 50% slippage and still have good traction. found 20% is best slippage for maxiumu speed and traction.
So maybe with that much variation using current it is possible.
