It might show up on the flight data monitor so best to own up rather than get pulled in by the safety department. Recovering with a 750’ height loss isn’t too bad but obviously being close to the ground they couldn’t afford a massive drop. An early recognition and prompt recovery action probably helped.
Simulator stall training often involves the fully developed case at higher altitudes where the height loss is significant and the time involved lengthy before the aircraft unstalls. More emphasis on recovery from low altitude events minimising height loss may be called for.
