Any Further Than Follow-Through And You MUST Swivel
Just remember, everybody, that once you've completed the Follow-Through (Both Arms Straight position with the Club about 45 degrees to the ground), you MUST begin your Finish Swivel (12-3-#41). If you don't, the Club cannot complete its proper route. And because your Computer knows you are not going to Finish Swivel, it preparesduring the Downstroke for the coming dreaded Chicken Wing. As a consequence, Power and Accuracy evaporate.
So, practice hard that Flat Left Wrist with Basic and Acquired Motion shots going no further than the Follow-Through. But that's it! Any further, and you MUST Finish Swivel.
I'm a right handed player. When I think finish swivel I make sure to keep my hands moving "left" after both arms straight all the while trying to keep a bent right wrist (flat left). If I don't think "left", my hands go down the target line, my hips stop and I block the shot to the right. Or, I flip.
If you keep the hands moving down the target line you will chicken wing it. If you move the hands "left" while attempting to keep a bent right wrist and flat left you will swivel. The hips WILL follow and the club re-planes itself.
