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?

UPP in snowy but warming Ohio

UPP-Here is where I think you missed it and where you got it.
A) You got it - in the regard that you are visualizing the center of the shoulders i.e. the neck/head staying level.
B) Where you missed it- is that the primary lever assembly- is not the entire power package and it is not the center of the shoulders i.e. neck/head- but it is the left arm/shoulder and golf club.
See if that helps - or see if you and I need to have an on-going simultaneous thread - like the one that I'm having with Matthew.

By the way- you are a positive thinker- I like that! OR did they give you back your job on the Ohio Tourism board? "Snowy but warming up" come on Bob! What did it go from -10F to -5 F? That's pathetic!
