I don't think so. The incipient recovery is all about reducing the angle of attack which should stop the autorotation. Wheras the increase in rotation as the recovery is effected is a characteristic of the fully developed spin of most aircraft. This is because as you move the control column forward, the moments of inertia are reduced and the spin accelerates. I've noticed it on most of the aircraft I've spun (including the Z242) and it is something that was included in the standard CFS style board brief prior to flying the exercise.

Aerobatic aircraft which are designed to be spun a lot have superlative control in this aspect. Even an aircraft such as the Extra 300 with a zero degree incidence symetrical wing will recover from a spin alamost as soon as the contols are centralised. I can't say I remember the spin accelerating as the controls are centralsed - largely because it happens so fast and my brain works slower!
