I think the question has been asked but I couldn't find an answer so I'll bring it up again as the endless belt effect is such an important concept.
Approximately where is the "release pulley" located? When looking face-on at the golfer, is it near the right knee? Is it further "up/down" the delivery path? Or is it simply a function of how much trigger delay the golfer is using?
If it's a function of trigger delay, is there a "probably-shouldn't-be-located-more-down-the-path-of-the-hands-than-here" location?
