In this plane the closer the right hand goes to the right shoulder - the greater the angle between the upper arm and the forearm. This always creates a triangle shape between the right shoulder to hand - right shoulder to elbow - elbow to hand, except when it is inline. It is actually the right shoulder to hand line that is the third line on the law of the triangle per chapter 6.
PS - Im looking for this to be a active discussion. If you have any input to give or feel you want to add something - please discuss

Just a small trivial thing- but to keep everything crystal clear- the more the hand is closer to the right shoulder- the "larger the angle" is what you said. So for me that's looking at it from the "other side", "the underside"- because I first think of "THE ANGLE" as the angle that is between the hand and the shoulder- and that angle gets smaller as the hand approaches the shoulder. So you are talking about the angle getting greater because you are looking at it as if there is a circle that passes through the shoulder and the hand- and as the hand and shoulder are moving closer together- while the angle between the two get smaller the other "angle" of the 360 degree circle gets larger.
Have I got it?
Also, Matthew - some very interesting stuff- but I've got to understand it before I give it the rave reviews that it might deserve. I'll get there just need some time.
Thanks,
Mike
P.S. I didn't pay attention to your second drawing- which clearly shows how the context in which you are referring to a larger angle when the right hand is closer to the right shoulder. You are taking the angle from the right shoulder as I was looking at it from the right elbow. Maybe your description of the "greater angle between the upper arm and forearm" could be improved.
