Not many sir. The majority for sure are fairly late or somewhere in between "latest" and "earliest."
The earliest that come to mind at the moment are Tom Weiskopf (from what I've seen), Tom Watson, and Johnny Miller. (from what I've seen)
Why do you ask?
Got any ideas?
Why do you ask?
It settles the matter of what is likely the optimum way to go about release.
Got any ideas?
” WHY do some people hit it further with an earlier release? ”
Perhaps by obtaining improved clubface impact conditions with an early release. Instead of chopping down creating a more elongated sweetspot.
” Why can they generate more speed? ”
Some people likely generate more clubhead speed with a non optimum swing. Hence there might be a max speed swing vs. most efficient swing, not necessarily the same for a particular golfer.
"I understand it has to do WITH hand speed......or at least this is what you've found Brian......
But why does this make for a loss in speed? How does it work?
When trying for a later release, do a person's "slow hands" cause the pivot to also slow down just so the hands can "keep up"? ”
Each golfer has a very personal way of generating torque during the down swing. It determines subsequently the forceful unfolding of the golf club which determines largely what happens to the hands during impact.
If torques are produced aggressively right from the top than most likely hands appear very quite during impact. However someone starting very smoothly and trying to peak around or even beyond impact will have somewhat more motion of the hands through impact.
An aggressive sit down motion ala Tiger generates lots of kinetic energy from the very start and leads more readily to a down swing having very ‘quiet’ hands through impact.
Hands are merely attached to the arms which are connected to the upper body. Two swings could have identical clubhead impact velocities but nevertheless show noticeable difference in speed for the hands during impact.
All this matter is riddled with feel vs facts. It could however be rather easily settled doing measurements using a skilled golfer able to swing repeatedly and consistently in a variety of ways. Just patch up Brian with some appropriate gauges ..........
