Golf2much,
would it be possible for you to summarize and explain this thread? Or Matthew? Or is this some sick Bucket trick so that I'll cut my own head off! I guess I could review all of the posts in this thread- study them - review them- and then try to understand what is parallel to what, etc. but I'm a little worn out.
Thanks

I'll give it more of a go in the AM. This thread required some serious thinking on my part, and I'm still not sure I get Mathew's full intent yet.

For the first part though, think about a swing fan(one of those training devices) Swing it like a golf club with two blades aligned to your inclined left arm plane. The blades that are 90* to this inclined plane represent Jen's plane and are aligned along, but vertical to the plane of your left arm. As the fan is swung, imagine what happens to the Jen's plane blades; they close to the inclined plane like the book example as you approach impact, and as you approach finish, the lower extension of Jen's plane (the bottom, initially vertical blade) passes through the inclined plane and approaches vertical to it. In short, starts vertical, goes to and past parallel, and to the opposite vertical.

The wrist cock part and it's real world application, I'm still struggling with.

Sleep well
