Acquired motion question

[garagefan66]

I love practicing with acquired motion and thought I was doing it correctly until I started going through Yodas lessons with Colin Neeman. I have a hell of a time keeping the clubhead below the hands. Is that simply over acceleration? And, how important is it? I hit a lot of solid shots going right forearm to right forearm. Any suggestions would be welcome. The Colin Neeman videos are great. I learned my finish swivel was wrong too (breaking the left wrist). I guess I still have a long way to go.
