I couldn't find the photos last night so I can't attempt any
measurements of wing deflection. The scenario I imagine is this. The
pilot makes an agressive contest finish pull up. The pull up starts
at over 100kts, the pilot continues to pull as the speed decays to say
60kts where the wing experiences an accelerated stall.

If he waits to 60 knots, he is well into a loop. Based on my contest
finishes, I'd guess he'd be back at 1 G before the speed decreases to
85-90 knots. The high G part of the pull-up is very short - just long
enough to get the glider aimed upward.
