Please compare the photos 8-3 through to 8-10.

I presume these are posed photos in a controlled environment to "model" correct movements. There is a small amount of head tilt to players right on the backswing ( using stationary ball as the fixed point) BUT by "Release" (8-9) there is the "appearance" of some forward head movement BUT by "impact"(8-10) the head has moved back to original position.

Is this "appearance" real ?

Is this the desired head movement?

Is this an oversight in these photos?

One of the basic tenets of 'how to study' TGM lies in how to interpret the photos accompanying a given discussion. On this point, Homer Kelley was adamant (2-R):

"The picture presents the subject only as noted in the written discussion and is not intended as a reference regarding any of the other aspects or subjects which the picture may include incidentally."

In other words, don't be looking at her Foot position if the discussion is about the Hips. Or the Knees if it is about Delivery Path. I have said many times, "If the subject is Right Anchor Knee Action, and she is hanging from the ceiling with her Right Knee bent, then the photo accurately depicts the point under discussion."

This is the point missed in the quoted reference to the photo sequence in Chapter Eight. The photos depict only the twelve sections of the stroke and their boundaries. That is the constraint of any analysis, and any other Component relationships depicted -- Feet, Knees, Hips, Shoulders, Head, whatever -- are incidental and therefore not to be relied upon for their accuracy.
