He started his downswing with a hip turn-and a shallowing of the plane "feel".
Is that a hitting proceedure?

That I dont think have to do with it. The reason he did that is cause he uses the shallowest plane possible with very deep arm position.. If he don't do that, he will have too much inside out = Hook. He need to start up with a more rotary hip motion so that the plane will be more square... The most important thing is to move the hip parallel to the plane line...

I don't think hitting is necessarily a turned shoulder plane. or 10-5-E.. TGM have choices. 12.5 1 and 2 is just a "guideline"

Hogan definitely knows how to shape his shots and that require a different impact and vectors alignments.
