I think of impact interval as a circular motion by the club. The motion of the ball is a little more complex I guess. After all, the ball is being quite deformed and doesn't get back to normal shape before it's in the air.
I'm not sure what Homer said about a perfectly straight shot. But based on his impact drawings in ch two, i would say that a straight shot with as perfect as it gets compression would require a vertical hinge. Becaus a horisontal hinge would impose the rotation rate of the hinge itself on the ball. So even though we assume that separation occurs at low poing and club face pointing towards target it will be a small draw. But we are perhaps talking so small that it isn't even measurable.
Seems very reasonable to me. I would have thought an angled hinge so I have to think about vertical now.

This is just a excample as I know very little about how the ball behaves during impact in detail. But there's no doubt that there is som serious redistribution of mass going on in the ball during impact. Elastic deformation. Of course, how the ball deforms and how it recovers will have an impact on the ball flight.
Sounds perfectly reasonable to me and makes sense as a possible outcome.

Yea, certainly a field of study I need to learn more about to have real technical discussion on the subject. Any ideas on sources of information on this area of study?
