Here is some real disturbance,

(Berndt in blue)

"CF doesn't produce any swing speed... there is a CF/CF pair alive... Caught in the middle you have a cocked left wrist... The two forces pulling from each side of the hands will cause or contribute to uncocking of the right(sic) wrist and release."

So he says CF doesn't produce any swing speed, but does cause the wrist to uncock, which does produce swing speed! :confused1

Even more disturbing is the fact that he ignored my question about Hitting and gave a presentation on Swinging. :(

Finally, since CF is preempted by muscle in Hitting, then I personally consider it not only unused, but nonexistent as well.

LOL,

At Impact, the Left Wrist is Vertical, so the Left wrist is moving the Clubhead "Straight Up and Down"? Right? And how is that a forward motion?

"Magic of the Right Forearm": as CF causes the Left Arm to Blast off the Chest into it's own Orbit, the Right Arm begins Straightening. The Uncocking Left wrist merely accommodates/synchronizes Changes in the Triangle Geometry. HK Calls the #2 Accumulator "Velocity" because the Clubhead is overtaking. But it's not overtaking the Right Forearm Wedge (the right wrist remains Level and Bent) and it has no effect or change regarding "Rhythm" (RPM).

When Uncocking the Left Wrist causes Clubhead forward motion, then a bent left wrist at impact is inevitable.

Furthermore, as the Left Wrist Rolls past Low-Point, the Left Wrist continues to Uncock (The Left Wrist is Level at Impact) and is therefore going "Backwards" (Direction) until Full Extension.

No, it does not.

CF only has an outward reaction force directly in line with, and equal to, its CP originator.

To add force would require CF to be tangential to its CP originator - and it aint.

If you prefer to be confused I can't help you.
No I didn't. Read the last sentence one more time, please...
Then what causes the club head to move along a curved path from top to finish? Feel free to invent a new physics and explain to the masses.

Daryl,

I'm not sure whether I was the target here or not, but I don't see anything in there that I disagree with.

I was LOL because (DARYL RED) was followed with (Berndt in blue). I thought that was funny. Good, but funny.

I think that were all pretty much on the same page with Throwout and Driveout.

Anecdotal Analysis
 

Back to the original question.

A little anecdotal analysis;

I have seen data-can't locate it at the moment- that shows a golfer swinging with , left only, right only then both hands.

As I recall the results were approximately:
Left Only - 85 mph
Right only - 90 mph
Both (normal) - 105 mph

Conclusions;
Neither hand can produce the power both produces so swinging with either hand will be better if the other contributes.
The power is not a sum of the individual powers - if it was the result would be the (approx.) the square root of the sum of the squares of the p-ower from each hand.
[SqRoot of L squared + R squared] (would be about 124 mph in this example)

Even if there is only checkrein action by the left for hitting it is circular therefore cf exists.

It is very likely that either swinging-left hand or hitting/swinging Right hand , a substantial cf contribution is necessary.

Just me thinking.

HB

Because the left arm/club is attached to the left shoulder and the right triceps pushes on them - pretty basic grade school level physics. You don't seem to be able to grasp the fact that in Hitting, the left wrist is uncocked solely by the right triceps. :(

The uncocking right elbow directly and completely uncocks the left wrist. The shaft does not freewheel through the release interval. :study:
