It's probably somewhat of a moot point what the motor, gear ratio, etc. is I would think. Just by it's nature, back-EMF cruise is totally incapable of keeping perfect sync with external wheel motion. It's analog nature gives it no way to synchronize exactly to the mechanical motion, some slippage is inevitable. Trying to have perfect sync with internally generated sound using back-EMF would be a fool's errand over any length of time.
That's not to denigrate back-EMF cruise, it's a very capable system, just not suited for exact mechanical synchronization. I'm perfectly happy with the cruise performance of boards using back-EMF, that would be a different topic.
