[O.B.Left]

At Impact, even on the Turned Shoulder Plane, ideally the Left Wrist is Level. Therefore, there will be an angle between the left arm and clubshaft. It's reduced because of the necessity to reduce the #3 Accumulator Angle to use the Turned shoulder Plane, but it nonetheless exists.

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

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.
