[12 piece bucket]

In the edit I did on this youtube:

Whilst accumulator 4 has not started to release (ie. the initial move before frame by frame segemnt) the left shoulder moves left without much vertical motion...John Schlee (and hence Tom Bertrand) always go on about moving "level left".

Then there is much more vertical motion in the next sgement (frame by frame)...

Obviously it is all blended....but the pivot is much more complicated than just pure rotation. I'm sure that Jeff could do a great job with his Spline tool on the motion of the left shoulder and left knee....maybe "j" shaped...?horizontal during lateral weight shift and preliminary rotation (about 45 degrees) then much more towards vertical when the axis tilt kicks in ???

Maybe?

Cool . . . you can really see #4 releasing there.
