I think that is reasonable, and thanks for your patience. What makes it suspicious to me is its connection with a mechanism that exhibits that precise artifact in rare though actual circumstances. We'll see.
Statics? Quite agree. especially with the ROLL coupling the AoA. For that matter, the airframe was in very untrod territory, all bets off.
Just to be clear, I am noting the zipper trace at prior to ap loss. I do not take that to be AoA fluctuations, there isn't time enough between 'cycles'.
