There is no need to be precise, so long as your backlash compensation moves go the right way and are more steps than you have backlash combined in the focus motor and focuser, no problem.

Agreed. I used a fantastic method to measure my backlash accurately using a dial gauge, and added the necessary compensation into NINA based on that. Should be easily doable on any focuser.
