Having attended the Summit I can tell you that what Dr Zick showed me was that the ball is struck from the inside but that it is not as much as "some" have been led to believe. It is perhaps a "dimple" or two from the center and not the entire "inside quandrant". This topic has really been made more of than it probably deserves. The real debateble (sic) notion was that horizontal and angled hinge action cause little or no effect on the flight of the ball. I still am not totally sold on that one just yet. The summit was a great time, only around a couple dozen attendees though. I was wishing there would be more to meet.

The effect of the hinging has a direct relationship to how fast the door is closing.

The faster the hinging motion, the more spin is applied to the ball. For example, the faster, or further, preferably both, the club face moves counter clockwise around the ball between impact and separation the more hinging effect, will result.
