Does this shed some light on what's going on....there's lots of frames here to examine

Not even close. You don't even have 30 frames. Until you see a golf swing at 320 frames a second you will not have a clue what is really going on. This is one of the biggest reasons golf swings are analyzed incorrect. There was never enough frames to see what is really going on. Now with the new Casio camera or cameras like it, is and it is going to change the way we analyze the swing and make corrections in the golf swing.
