Cool! I kept wondering why did the pics just go straight from Impact to Finish . . . ON EVERY SEQUENCE?
Here's what Iron B had to say to that point . . .
RELEASING HAND POWER - At this point in the swing . . . (Release) I have the sensation of my right hand trying to catch up with my left. . . . The left hand is not turned (rolled) over, and will not do so during the entire swing. . . . this method increases accuracy and consistency. It is a sure cure for the common fault of rolling your wrists (turning the left under and the right over, as the clubhead progresses into the follow-through stage of the swing).
Not only did Byron take out the revealing photos, he specifically states in the text above that the correct action -- Left Hand Roll (Hinge Action) and Finish Swivel -- should be avoided. Further, he embraces the incorrect action ("the left Hand... will not [roll] during the entire swing").
Again, all this is simply out-and-out Steering -- the First Snare (3-F-7-A). Despite the logic of the message -- "seems as if" -- and the immortal status of the messenger, the advice is wrong. Those who take it will have climbed aboard the 'A' Train to Hackerville.
