My point that I'd tried to pass over was that for experienced pilots the sudden slat opening did not make them jump or feel unsave and some good ones learned to just drive the 109 at the point when the slats were open in order to increase turn performance at will.

I do think that pilots coming from the flight school might have experienced and taught slat opening a little bit but not enough to feel comfortable with slats springing open. Compared to experienced pilots or veterans they are a bit like new owners of a driving licence compared to Michael Schumacher.
