The Elbow Plane, has only a "2" stage acceleration sequence. Hand acceleration and pulley release occur almost simultaneously. There is no straight line into the pulley. Hand and Clubhead acceleration is a single event.

I don't agree with that. And I'm fairly sure Homer Kelley would have said that you can have Snap Release on an Elbow Plane.

Hand Acceleration is the entire interval from the end of the Start Down until the start of Release - Section 8, Downstroke. With a Double Shift and Angled Line Delivery Path, both the vertical path of the Hands down to Elbow Plane AND the straight line path of the Hands from the angle towards the Aiming Point are Hand Acceleration and precede the period of Clubhead Acceleration.

Compare picture 10-23-B #3 with pictures 10-24-D #2 and 10-24-E #2.

To me, 10-23-B #2 shows a Snap Release on the Elbow Plane. 10-24-D #2 and 10-24-E #2 show Snap Releases on the Turned Shoulder Plane.
