Hogan doesn't take his own advice!

That's the whole point. Yoda explained this in the PGA summit, that Hogan felt extensor action, but got it wrong when trying to explain what he actually felt.

Did Hogan move his right elbow away from his side in the backswing or keep it right tight against his body?

Take a look at the video once more - and you tell me.

I was only referring to squeezing the elbows together. It's clear to me that Hogan didn't use EA. And it's debatable whether or not he was actually describing his own swing in the 5L book.

It's a shame that Yoda isn't here any more. I can't speak for him, but I got the impression that he meant Hogan actually felt this tension (EA). How was his width - good width has to be done with EA I would think (?)

I think that BH was a #2 PP Swinger. No EA. He claims to need 2 right hands. Maybe not so unreasonable if the Left hand slows during clubhead acceleration.
