Well, without FDR data, it's hard to estimate when the seat envelope was exited. There was Thunderbirds' solo crash a few years ago, where the pilot made the gate on the top of the downward half-loop, problem was it was for the wrong, lower elevation field. He punched out relatively safely when he realized he could not complete maneuver above ground level.
