The real problem with this drill is that it is performed from the Adjusted Address position, i.e., with the Left Wrist Bent and Right Wrist Flat. Then, a perpendicular Left Wristcock puts the Club out-of-plane with the Left Arm, thereby destroying the Left Arm Flying Wedge.

Any Left Wristcocking drill should be done from Impact Fix (Left Wrist Flat, Right Wrist Bent) or with the Left Arm and Club otherwise in line. That is why, in my recently posted Left Wristcocking video, I demonstrate the perpendicular Cocking and Uncocking from opposite the Left Shoulder. Then, the Left Arm and Club remain in line, and the Left Arm Flying Wedge remains intact.

Again, that is not the case when the Left Wrist is Cocked vertically from its Adjusted Address, Bent Left Wrist condition. This condition normally is acceptable only when using the Turning Shoulder Plane (10-6-D) with its Vertical Loading Action, i.e., true Single Wrist Action (10-18-C-#3) with the Hands "under the Club" at the Top.
