Your opinions make no sense (to me).

You state-:

1) "I agree that the lag pressure point is driving the club. And by "driving" i mean adding energy to the club."

How does PP#3 add energy to the club considering that PP#3 is simply the right index finger against the back of the club?

2) "The point is that centripetal force doesn't add energy to the golf swing. It only stores the energy that has been added through the work of tangential forces."

How does a centripetal force store energy? Stored where? To what purpose? Is that energy eventually released? When, and how?

3) "The centripetal force that we have to produce to keep the club swinging is an effect of the velocity introduced by tangential forces."

Why is a centripetal force needed to keep the club swinging? You then immediately state that centripetal force is an "effect" and the "cause" of that effect is the "velocity produced by tangential forces". From where is this tangential force derived? When those tangential forces act to increase velocity - velocity of what? How does velocity of "what" produce a centripetal force?

4) "The tangential component is the one that increases the swing speed. It adds velocity energy to all the moving parts of the swing. The centripetal component changes the speed simply by changing the direction of the movement". How does a change in direction increase swing speed? Speed of "what"?

5) "More clubhead lag (the further the golf shaft points away from the neck) will mean a larger ratio of longitudunal /centripetal force."

Why? If the club lag is 90 degrees, why is there a higher ratio of longitudinal/centripetal force compared to a situation where the clubhead lag is 75 degrees?

6) "The actual golf stroke is an harmonic blend of tangential force that builds speed and centripetal force that purely helps us store the speed that's already there. You need to apply a centripetal force of increasing size to account for the ever increasing energy that is accumulated by tangential force."

Where does the centripetal force store the speed? If one uses a tangential force to move "what" why is energy accumulated? If the swinging "what" travels at a faster speed, why must centripetal force increase?
