This obviously shortens the Swing Radius considerably because it now only extends from the Clubhead to the Left Wrist rather than to the Left Shoulder. It moves Low Point forward -- rather than being opposite the Left Shoulder, it is now opposite the Left Wrist.

But surely a Long Drive Champion such as David Molbey wouldn't be using an inferior procedure like this. He has one of the slowest clubhead speeds in the business, yet he is one of the best. Could this be the reason why?

How can TGM explain this?

Lets say he does this because he wants to hit down on the ball. But what's the advantage of this procedure compared with the standard one where you just place the ball behind the Left Shoulder without changing Low Point location?

I have more comments later. I'd like to hear what you guys have to say.

I am not so sure that Mr. Kelley will actually classify this as a shortening of a swing radius.

Per 7-17, halting the backstroke with the feet and letting the same tension pull the Downstroke through Impact is "swinging from the feet" and gives the Stroke maximum Swing Radius.

The difference between this look that Mobley exhibits and a bent left wrist at impact is that the former does not result in disruption of clubhead orbit and throwaway, while the latter does.

That Mobley is Long Drive Champion despite a "shortened swing radius" proves that there is more to long drives than just pure clubhead speed.

Per 2-M-1, power is mathematically expressed as 1/2 Mass x Velocity Squared.

Per 2-M-2,
Mass is varied by Acceleration Rate and Swing Radius.
Clubhead speed is varied by Acceleration Time and Release Interval.

Other factors that need to be considered is centeredness of impact, wind, equipment etc...
