To be honest, that's the kind of question which isn't answered straight. Too much things can turn those nice resolution into thrash/mean nothing. I once forgot to do change/add new lubricant on the axis rod, and my print have a 2 mm offset on one direction, pretty sure PLA doesn't shrink that much.

I like to think the spec of the motor, nozzle are only an intermediate among a big process. Which means there could be anything before or after that can screw your "resolution"
