Just to clarify, the 1/4 inch ply is "rough cut" as closely as possible and the filler adheres to the wood and gives the smooth surface needed to re-profile? How far back above, and below the wing do you go for a glider you want to perform well?

You understood correctly.
First 10% or so. About 3 inches inboard and 2-1/2 outboard.
Purpose of the templates is to have finished wing with same profile it started with. "Normal" sanding will usually make the leading edge too blunt.

Next step ? So you then wax the female end of the template and fill the wing stations and place the template into the filler . Remove and that becomes a screed point between stations?
I've seen a recently refinished wing that had lots of small cracks every few inches on the leading edge . Bad filler product? Does the filler shrink ?
