I am not interested in accurately measuring pelvic sway motion because it does not change the way I think about performing the downswing pelvic motion in a full golf swing action.
I watched the part 1 video with Dr. Kwon, which I found non-insightful and of no value. I think that he ignores the specific biomechanical effects of pelvic girdle muscular action and that makes his opinions useless from a golf instructional perspective.

Thought I'd add this video I found where Dr Phil Cheetham provides a graph of average pelvic movement for 94 PGA Tour pros. There are quite a few other videos on this 'Skilled Motion Science' you-tube channel by Dr Cheetham. If you look at the graphs and the previous one I posted (ie. the one just above) , it shows that the pelvis/ribcage is 'shifting & turning' in 'their' downswing before P4 is reached. It seems to be a way of utilising SSC stretch in the body segments. DG

DG Measuring the average amount of pelvic sway in the downswing in pro golfers is not useful because pro golfers vary as to whether they have a rightwards, centralised or leftwards pelvic loading pattern by P4. It is obvious that a pro golfer who has a rightwards pelvic loading pattern (where the pelvis is at the extreme right hand side of an imaginary barrel opening at P4) is going to have much more targetwards pelvic shift during the downswing than a golfer who has a leftwards pelvic loading pattern.
