I got an interesting comment from someone. What they said is very true......."If you learn to make your [Hogan] backswing right with slow motion (according the camera) it can be something totally different with normal speed".
My main roadblock in the beginning was the difficulty involved in analyzing Hogan's real speed swing. I had always heard guys say "you need to focus on the concentration drill." Well, I didn't trust that he was doing anything close to the concentration that he's doing in the real speed swing. Probably because I've heard so many people say that Hogan had a secret, and he took it with him to the grave. So I deduced that if there was a big secret, then why would he show it all across the world at ProAms and clinics. I was caught up in the "secret" belief. I was becoming programmed by the thoughts/beliefs of the golfing community. And when top 100 teachers spoke of this same "secret" I figured it was the gospel.
Then, just for fun, I decided to put the slow-mo of the real swing, vs concentration, side-by-side; and compare dynamic movement as well as angular position. From the waggle to the top, I was shocked to see that they are just about the same movement, dynamic, position, etc. Nothing secret when I saw them side-by-side broken down. I am now transitioning from experimentation to major focus on the concentration drill.
I do agree that doing it in super-slow snail-paced fashion is much different than at rattlenake-strike pace.
I'll just start working at .0000000001 mph and ease it up throughout the years.
Current "concentration drill" focus will only be the waggle and setup. This could easily take a year, but who knows, I could get lucky and have a learning spike.
