Are you hitting or swinging? The hitter tends to carry the club back and keeps the clubface "looking at the ball". The swinger will use a start-up swivel which tends to put the clubface "on the angled plane" during start-up.
That's the great thing about TGM.... "it depends" on what your pattern and preference is. There is no "this is the way it is". So much more precise and with so much more "here's why"!
