CLUBHEAD THROWAWAY

[DES]

Could someone explain the differences between 6-D-1 AND 6-D-2? I am assuminmg that 6-D-1 is CASTING, of which I was guilty, and work on every day. I think I understand 6-D-3, but don't see the difference between 1 and 2 -- 2 appears to be a "casting" as well.

In 6-D-2 the early release is an effect of overacceleration, while in 6-D-1, wrist action directly executes the early release.

Both are casting, 6-D-1 is an early throw from the top, 6-D-2 is a loss of lag in the downswing which causes the right wrist to loss its “wedge” and flatten. Study 6-E-2 - aiming point.

DES,
Take notice of the pictures - they help.
They all have in common the fact that they lose lag pressure.
They are are different in two ways- where they lose it and how they use it.
Where:
6-D-1 Loses lag at the top
6-D-3 Loses lag during release
6-D-2 Loses lag somewhere between 6-D-1 and 6-D-3.

How:
6-D-1 Throw it from the wrist to create motion versus hand movement.
6-D-2 Over acceleration.
6-D-3 Sensing that uncocking of the left wrist should align the clubface.

Of course, there are more, he just wanted to give you the basics. For example any off plane motion coming into the ball requires that you have clubhead throwaway otherwise if you maintained the pressure point pressure and thrust with no adjustments you would miss the ball. And I am sure there are other clubhead throwaway issues that could be described and categorized, if you had an interest in pursuing that, another potential area of exploration and explanation for The Golfing Machine.

You might have wanted some other answer to really get it or understand your confusion - so keep asking, and I am sure there are others that might have a different angle that might be helpful.

The over acceleration is a reference to? hands? clubhead?

[Mike O]

It's the lever assemblies - which include the hands, the clubhead, the shaft, the left arm which if start down to fast, you as a person just can't maintain that rate of acceleration past impact, and at the point you cease to accelerate you will experience throwaway. But the place that you monitor or sense how much acceleration you have and whether you will have or do have throwaway is the hands. So back to your question hands or clubhead?- the answer would be hands i.e. "the hands are initally over accelerating based on the length of downswing distance they must cover and the maximum speed that you can move them and your solution would be to reduce the acceleration or shorten the stroke.
