I cannot fathom why you presented the last three photos of Tiger Woods.
You have drawn a red line through the ball at impact and stated that the hosel is not on that plane line. Of course it cannot be on that plane line if the sweetspot is on that plane line. At impact, the hosel and sweetspot cannot possibly be on the same plane.
However, they are on the same plane at the extremes of the impact zone.
What can one conclude other than the fact that there is only a very small difference between the clubshaft plane and the sweetspot plane within the vicinity of the ball (roughly within 1 foot of the ball) while there is virtually no difference as one gets closer to the third and fourth parallels? Also, the difference between the clubshaft plane line at impact and the sweetspot plane line at impact is very small and of no apparent practical significance.
If I drew the red line from PP#3 to the hosel, I would be able to demonstrate that the hosel is also very close to that red line when the clubshaft is near the third and fourth parallels. I personally don't think that my demonstration would help to clarify matters.
