I agree with Genghis but don’t like his half turn pro – I would think a couple of turns or more might be needed to do the job in some cases.
Spinning is one of those pastimes that produces occasional odd balls. It always has and anybody who is deliberately doing it without plenty of height (to say nothing of not having a parachute) is taking some degree of risk especially if they (or a student) use a vaguely executed or non standard entry or do not maintain the 100% correct recovery actions for at least two turns in the event of a problem,
