So -many planes:
Get them all "guessed" at FIX and they all change at impact.
Here is a big one.
COG pull causes toe down at speed.
The shaft is now bent in an arc.
the grip now points, not at the hossel, not at the cog but, because it is a tangent to the arc of the bent shaft caused at toe down, out beyond the toe of the clubhead. But how much? What is the correction? how is it added? Tell me what becomes the feel at pp #3?
Not an Easy Riddle.
Hint- I have posted the solution as I see it some time ago.
