For all the responses and I understand what has been said, BUT it is clear I am either missing a major factor here or ....

If the Clubshaft is to remain FLAT against the Inclined Plane having a Straight Plane Line and the Sweet Spot Plane Line is also straight you can if you rotate at the correct rate, one and only rate to maintain those relationships.

Since Hitters and Swingers 'Swivel' in the Back Stroke at different rates makes this impossible to maintain the above relationships UNLESS the back stroke speed of a hitter and swinger must be different, the hitter having the slower back stroke.

Also if we could easily quanitify this rotation rate per back stroke speed, we could provide a key for a golfer to remain On Plane,.

As for the Down Stroke, same problem exists.

And none of this accounts for LAG or Droop which will again affect the outcome.

One thing we all should be able to walk away from this discussion is that you DON'T want to monitor the Club Head, you DON'T want too focus on the Club Head. It has to be the HANDS else the uniqueness of the stroke will be very open to inconsistencies and create a number of TGM 'X' Components.
