I dont know what you mean about the wrist bend and release , where is that covered in the book?

The Bent Left Wrist Release, AKA the Hogan Swivel, is not the Recommended Procedure. It's unnecessary when using a TSP. All available non-recommended procedures are not included in the Book. The Hogan Swivel is only one of many ways to reconcile clubshaft vs. delivery path angles so that both halves of release can be executed while tracing the same delivery line.

Keep in mind that by sacrificing the Left Arm Wedge and Flat Left Wrist until Impact, makes sensing drag at startdown more difficult. Everyone has felt how much more heavy or resistant the club feels at start down when everything is aligned on one plane.

In the above quote you seem to be saying that a TSP angle at Impact is steep. What Im saying is that the TSP angle steep though it is, is not an angle for Impact but more of a Startdown plane angle prior to a shift to a lower plane. The impact plane angle must be the clubs lie angle in terms of degrees vs vertical. So if you were to make contact on a TSP angle it would have to be an extension of the clubs lie angle that bisected the turned right shoulder at top. Cant do that with all the clubs in your bag very easily. Maybe if you bent the lie angles on every club to conform to where your right shoulder turns to or something.

7-6 BASIC PLANE ANGLES The Clubshaft must starts its journey on the Plane of its Address angle of inclination. It may or may not move to the other Planes as it travels. Clubs cannot be designed to be perfectly Soled (2-J-1) and still align the Clubshaft with more than one Plane Angle Reference Point. So those aligned between the Elbow and Shoulder Turn Planes have become the most widely accepted, because actually the Toe or Heel can be lifted enough safely accommodate either of the flatter or steeper Plane and therefore any listed Plane Angle reference Point (2-D-0). Even on hardpan, the Ball, normally is gone before the ground is touched. Then too, there is always the true Clubshaft Angle with 8-6 and/or 10-6-E. The ideal solution is a slightly rounded Toe and Heel for all Clubs. But also study 10-24-F.
