But, am I wrong or did I read somewhere, perhaps a long time ago, that Hogan was double jointed, just like Garcia? And would that ability to create huge lag because of this also contribute to power?

I don't know about double jointedness, and I can only imagine how his auto accident affected him physically. But as far as Lag is concerned, all of the answers are correct.

But, HK conceived that the further the right elbow traveled before release, more Clubhead speed (endless belt effect) would be developed. So, by geometry (and physics), not additional effort, one can generate more Clubhead speed. ((i hope I got that right)
