I have a question on system resolution.

After setting up a surface to travel thru its entire distance using 140% ATV
(in the end point adjustment screen), does reducing that travel by
DUAL RATES reduce its resolution?? Or does it only reduce travel.

Example:
Elevator.
End points set to 140 in both directions.
High rate set to 140% = 32 Degree's of movement up and down.
Low rate set to 65% = 15 degree's of movement up and down.

In the above example do I loose system resolution
on the Low rate setting?

Radio is a 9CAPSuper.
