Intersting stuff. But for the purposes of discussion can someone please define Snap Release. Let's all get on the same page here.
And at the risk of preaching to the choir I'd like to point out the benefits of earlier than snap as utilized by Mr Hogan. release point being a Machine adjustment . Jack couldn't hit a sky high cut 2 iron without Random Sweep!!! Luke Donalds sand shots wouldn't work with a snap release !!
For practical purposes, the shaft should be horizontal or above when the butt of the left hand reaches the right thigh on the DS. Some snap releases are snappier than others.
Kelvin Miyahira has identified a few "extreme laggers" in his publications. I haven't looked at them through "snap release" glasses, but I guess some of them are snapping. Like DJ, for instance.
I think Hogan had a later release (or hands more forward prior to the release) before he was hit by the greyhound bus, btw.
Don't relate the release to the right leg, a snap release is as if there were to be no release at all the last possible second and then instant swivel the butt of the club in a line of sight with the ball and and the shaft horizontal is snap for a short iron. I haven't seen a name yet...
