[12 piece bucket]

Not to my understanding, the hands from the top move right along, I mean never leaving, the line I drew for the TSP, the right forearm when he gets to the delivery position gets very close to the elbow plane (between the TSP and Elbow Plane) but the hands and clubhead are on the TSP.

This is what you're gonna find with MANY MANY pros . . . . they find a way to get the CLUBHEAD on the Elbow Plane . . . hands may not be there but the clubhead is . . . . he gets that clubhead out there . . . wipe city.
