"if you are talking about the angled plane that goes through the inclined plane vertically and not one of its other infinite possibilities. This plane will be the same as Jens plane when accumulator 3 has turned directly towards the inclined plane."

Matthew;

Never was I debating the importance of these details. I'm an engineer, and spend my career simplifying complex intangible things for non engineers. I understand what you have said in the above portion of your post, but if the "new" plane you mention is the same as Jens plane under certain conditions, then isn't it really just Jen's plane in a different position? Jen's plane as I see it is comparable to the degree of rotation of the left wrist hinge pin rotating from vertical at the top to parallel at impact and then to vertical below (or approximately so) at finish, much like your book cover example previously.

BTW, your graphics are excellent, and have been my key to understanding many of the more complex relationships. I can almost see them in my m inds eye, but your graphics generally cement them. Thanks for the great work.
