Another detail......

The amount of throw you have available can often mean little with gliders. We very often learn to use just the amount of stick (control stick movement) to cause our glider to do what we want, as much or as little as we want, and as fast or as slowly as we want.

So very often, we use lots less control surface movement than is available.

One goal that is worthwhile for glider guiders is to tune the mechanics in the glider to match the max physical throw to the max aerodynamic throw required. We often fly our planes with very little stick movement. And we often have airplanes that'll do very fast, wild things with very little surface deflections. And it's to our advantage to have those airplanes need 100% of the throw from the TX stick to give those little throws in the airplane.
