Here is a photo of BM at his Anti-Summit. He was mocking this TGM diagram that is often used by TGmers to explain the geometry of impact. Brian stated that he has never seen such a large divot wedge in a "real life" golf swing - Brian called that triangular wedge the "size of a slice of a Pepperidge chocolate cake". That's crazy! That diagram is only drawn that way for "conceptual" demonstration purposes. Note how far the ball is behind low point. Note the clubhead attack angle (blue angle) - it is drawn at about 30 degrees. In reality the negative clubhead attack angle is ~ 5 degrees - which is less than one minute on a clockface. That would produce a shallow divot. Brian also stated that a "real" golfer produces a divot that is less deep, because i) the left shoulder socket is moving up-and-away at impact and ii) the left hand is moving upwards (which he calls the parametric acceleration phenomenon). Do you believe that i) and ii) can shallow the divot depth without altering the negative clubhead attack angle at impact? How is that possible? Jeff.
