I continue to be reminded to look at the picture in 2-C-2 and every time I do I see more questions.
For example, in 2-C-2 #2 and #3 it clearly shows a leaning forward shaft at impact and a vertical shaft at separation.
Surely, we can all agree that is an inaccurate representation of what happens in the time frame while the ball is on the face as depicted in these pictures.
I certainly agree with everyone, that vertical hinge action can be a wonderful teaching tool in the real world.
Am I the only one that see's this and has a desire to question it and learn more about it.
Is the picture an exaggeration?
If it is, is the whole thing an exaggeration or just the shaft depiction?
How would I know if just reading the book?
Should this picture be changed in the 8th edition?

The problem seems that you are asking for Left Brain answers to Right brain questions drawn from left brain information. Or vise-verse. Or maybe I have it wrong. BUT I understand the represtation on the sketches. I would appreciate seeing your re-do of the informatin in those sketches to also include your suggested scaleing and drafting. Please post or link so it can be seen.
Take a ball and mark some "equators" on the ball so that you can watch rotation. Now, place the ball against the palm of your right hand and move your hand through the three hinge motions. Note the rotation of the ball for each. now in your mind realizing that the rotation is the same even for a very short contact interval reduce the contact to a differential interval(very small for the non technical) and accept the fact that the information transmitted to the ball is the same. You should note that the rotational information is unique to the hinge action employed. Therefore the ball flight characteristics will be different. That is good compression. You are carrying the ball on the original contact point to separation. It is hardest to do with vertical hinging or flipping the clubhead at the ball in a non lagging manner and it is sometimes amplified with a very lofted club like a 64 wedge (can almost hit that back over your shoulder with no compression) Play around with it for a while and you will feel these things- Have an epiphany so to speak.
Thanks.
