This better explains what I'm trying to say. The Left Wrist is Level and Flat at Impact for Both Procedures.

TGM's Turned Shoulder Plane requires a Release Swivel for the Left Wrist to return to vertical for Impact if the Sweetspot was swiveled to Plane at Start-up. We have ultimate control of the Clubshaft on a Turned Shoulder Plane with the Flat Left Wrist and full use of the #2 and 3 Accumulators. The Right Hand controls the Clubhead on every swing plane but it won't do it at the expense of the Left Arm Wedge when on the Turned Shoulder Plane.

The Elbow Plane needs the "Hogan Swivel" to change from a Bent Left Wrist to a Flat Left Wrist for Impact. I don't consider it a True Sequenced Release because all it does is spin the shaft around it's axis. It's like a Ball and Socket Swivel and can accommodate any plane angle with a lost Left Arm Wedge.

The Hogan Swivel needs to be Stopped to prevent over swiveling at or before Impact otherwise timing needs to be perfect. I think that this can be done in two ways. First, slam the wrist into an arched position after Uncocking so that the Left Wrist can be held vertical for Impact. Second, use pivot force to overcome the swivel as the left wrist becomes vertical. Arching doesn't need such a driving pivot and my experiments show that it doesn't have the timing issues either. Also, the driving pivot method, which is being talked about (force will create alignments), doesn't lend much confidence when face with a delicate 30 yard pitch shot.

If you Bend (Cup) the Left Wrist even only slightly, it is Bent and will require the Hogan Type swivel to prevent bending the Delivery Line.
