The problem here again is one of definition. Golfers talking to golfers with science degrees. Homers unique definition of the word mixed in.
I get the feeling no one is wrong above its just a matter of interpretation.
There's no cf (in the pivot power sense of the word ) for Drive Loading but there is cf present in the primary lever . Then there's Hitting with Pivot Power....
There AIN'T NO C.F. IN TRUE HITTING END OF STORY HOMER WROTE THE BOOK THE END GO SPEND Forty YEARS WORTH OF RESEARCH AND FELT BACK TO ME ALL YOU PIONEER'S IF GOLF THEOREM
The earth isn't flat even though Homer Kelley omitted to clearly state that it is round. But you and MizunoJoe use flat-earth-arguments over and over, and attribute them to HK and TGM.
There are a lot of people in golf who understand enough physics to see that your "there ain't no CF in true hitting..." statement above is pure nonsense. Absurd claims such as these give TGM a bad reputation.
Do U include any cf in your hitting procedure? if so, where, how, and how much?

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.
