How many positions can regulator 0-10v be adjusted?-modulating valve

How many positions can regulator 0-10v be adjusted?
If too many move position cause unnecessary movement?
Can your modulating valve regulator 200-300 positions? that's OK, no problem.

At present, we adjust the positioning error is 1.6 degrees, 90 degrees / 1.6 degrees = 56, So it can with 56 positions
If the customer needs to adjust more positions, just like 200 positions,that's also OK, we just need to do is reduce the error degree.
But this will cause the ball valve to constantly look for position, the ball valve will shake a bit, the motor life will also have an impact.
