My apologies if was not clear. My intention was only to provide a vocabulary lesson. I don't know if (in your situation) there is an issue or not. There are pros and cons to both methods and as the designer, you would weigh them against your needs.
Also, accuracy/resolution questions are not the only factors in determining motor/leadscrew drive ratios. Matching the motor speed range to the leadscrew speed is a major consideration.
