"I think understand, Tommyto is Derek Copeland using one of his
hundreds of aliases. "

Let us get at least this part straight - my name is Thomas Vallarino,
not Derek Copeland and I do not even know the gentleman.

"My measurements suggest the exact opposite - that increasing the
acceleration REDUCES the maximum AOA."

You can believe whatever you want to. You are free to disregard the
calculations in the analysis, the accident data and the experiences of
those here in this thread who describe specific cases of
uncontrollable pitch up movements, despite full forward stick - from
Karl's ASW-17 incident to the same experience of others including
myself with a variety of other models. It's not always the pilot's
fault when this happens as the pilot runs out of elevator authority.
The article calculated the pitch arm moment of many gliders and what
tension would be necessary to exceed the elevator authority at the
beginning of the launch. That's why they recommend a range of initial
rope tension of no more than 0.5-1.0g for singles and 0.7-1.0g for
doubles at the beginning of the launch.
