Where does the energy come from to accelarate the clubhead past your hands if your hands do not slow down? Newton and Gallileo pretty much nailed that you can't just create energy out of nothing. If your hands accelarate to top speed and then don't decelarate until after you've hit the ball then the clubhead cannot accelarate faster than the hands do and so you wont get a release.

You can't say that CF just does it. Put a free swinging arm on a wheel and keep spinning the wheel at a fixed speed - the arm will never catch up. It will only catch up if you decelarate the wheel. This is pretty basic physics.

Or am I missing something? You can't just take something someone says as gospel if the basic physics don't stack up. There must be something else added - so what do you understand that is?
