Don't like the upward movement immediately after impact through the follow-through. Probably a little throwaway. If you were to work on his game today- that's the area that sticks out in my mind and where I would concentrate on, at least on this clip. Could have been just this swing or that week that he was swinging that way, maybe wasn't swining it his best or could have just been his basic movement that he dealt with.

Mike,
Change this swing? I think there are two factors that should be considered before that.
I think that he’s just going for the smallest pulley possible. Stretching the left side. Shortening the radius.
Second IMO the differential in clubhead speed, pre-impact and post-impact, causes a near instantaneous change in the effective weight pulling on the left shoulder. Pre – impact the shoulder muscles are resisting a force (ever so briefly) in excess of 100lbs. After impact the dynamic weight of the much slower club is significantly less and the muscles pull the shoulder up and back.
That truly is poetry in motion. I could watch that swing over and over (in fact I have watched it over and over!)
Don't know about the rising left side. Has anyone read the Miura (I think that's the spelling) article on parametric acceleration in the golf swing. His research suggested that acceleration could be added to a swing through a motion directly opposite to the direction of the centrifugal force during the release stage of the swing. In fact, he said that this was the only way acceleration could be added at this stage. Maybe that's the rising left side we see in Hogan?
Anyway, aesthetically, that Hogan swing does it for me!
"acceleration could be added to a swing through a motion directly opposite to the direction of the centrifugal force during the release stage of the swing."
That sounds like the idea of lifting the handle through Impact. With Extensor Action, this will effectively give a manual uncocking of the Left Wrist by leveraging the shaft againt PP #1 or #3. This will slow the shaft rather than accelerate it.

Inspired by your comment I just did a little rotation experiment with a domestic pendulum device (my daughter's passifier with a string attached). And the only way to increase the rpm is to pull it in (more or less exactly) the opposite direction.
It would be interesting to see a more accurate mechanical description of this process.
