Use the maximum leverage from the servo, ie outermost hole and longest servo travel, the neutral position will be most accurate if maximum servo travel is used.

"maximum leverage from the servo"..............................
An analogy:
You're going to clean out the gutters on a house. You have an extension ladder. You use it first to clean out the gutters that are over the porch. The ladder is easy to move for that 1 story reach.
Now you extend the ladder so that you can reach the 2nd story gutters. The ladder is still the same weight, but it's much harder to move around.
Now you have to get the gutters in the back of the house and they're 3 stories above the ground. You extend the ladder to reach and the first time you try to move it, you can't keep it from falling over. Why?
The leverage has gotten worse and worse as you extended the ladder. The weight of the ladder has moved away from you.
So now pretend that you are a servo and the weight of the ladder (which never changes) is the aero load (which doesn't change either). Move the servo load away from the servo with a longer arm, and the servo is less able to move that aero load.
If you want to give the servo some help, make the surface control horn longer and the servo arm shorter. This always gets somebody. This time it got the git.....
Sorry I didn't make it clear, outermost hole in control horn, innermost on the servo. This results in maximum servo travel, creates leverage and so greatest accuracy. I guess I was starting from the horn rather than the servo in my poor description.
I am suggesting that the control is most accurate if the full range of servo movement is used. That results in the most accurate neutral point. My experience with servos is thirty years old maybe I am out of date and they operate differently. I will be glad to be corrected on this point.
