I'm not an expert, but perhaps I can relate my own experience.  I have two mounts...

My Meade LX85 is a relatively low-cost mount that has substantial backlash on both axises.  Because of the large backlash, it has difficulty making small movements during the align process.  I'm lucky to get the error under 300 arc-seconds.  I usually set it for 360 arc-seconds (1/10th of a degree) and let it go.  There is very little change from one step to another once it gets within a few arc-minutes.  Also, for most targets I don't need to be very accurate... unless it's full frame.

My SkyWatch EQ6-R Pro is a medium-priced mount that has little backlash and better step motors.  I can easily get under 30 arc-seconds in 2-3 steps.

I'm guessing that if I had a high-end mount (one of these days-- fingers crossed) I would get even closer.

Also, when the mount gets close, you are unlikely to detect movement as they are very tiny.

Hope this helps.
