How would you diagnose this, what would be the tell tale signs that one of your students had this? What kind of synchronization issues would tip you off?
I would define over-acceleration as a corollary of clubhead throwaway. If you find yourself swinging fast, even when you don't want to, then you are experiencing clubhead throwaway (overacceleration) and a loss of lag pressure points.
You need to be able to execute the stroke pattern at 1/4, 1/2 and full speed with equal fluidity and constant acceleration.
Ask the student to execute the full shot at various speeds. In my first few lessons my AI asked me to execute a 15yrd chip shot without allowing the clubhead to pass my hands at follow-through. I couldn't do it. I would always get a little bit of rebound as my club tried to pass my hands and jerked back.
This, he said was a symptom of 'adding effort' in the swing. Same thing as over-acceleration.
