Since the left shoulder moving upwards does this mean the whole primary lever assembly is also moving upwards? - Yes- this is a fact. NO- I don't see it that way- see my understanding above. But if we keep discussing this I should be able to understand your point or you mine.

I do not think so either. The primary lever assembly is staying level. The left shoulder rises but the right shoulder is going downplane. Then as the swing gets to both arms straight, that approximates low point assuming minimal throwaway....

How is that? Too simplistic?
