The AW guy is right. You want the servo to move as much as possible. This helps spread the pot wear more evenly across the surface. It also makes the centering of the surface more accurate and more repeatable.

But if you setup 150% and then use dual rates to cut it to 30% to 40% to get the throws you want, then the pot wear issue is still there. The linkages will have to be set up to allow the full servo travel and then give the control thows you need.
