'Muscle Memory', as it is known but in reality is actually a memory of the brain, enables the efficient repetition of a physical skill or a task but that is all. I do not know of any evidence that supports the idea proposed. The stall and the spin are only predictable following a particular form when it is deliberately induced. Glider pilots of course spend much of their time close to the stall particularly when thermalling. This stall will be of no surprise therefore and is repetitively practiced. Non of this is the experience of the vast majority of powered pilots.
