[Max Impact]

Glad to see you on the scene here, Yoda.

If I may....It is a widely-accepted condition of the impact collision, scientifically, today, that the ball starts off in a direction which is, on average, in the neighborhood of 80% of the difference between the horizontal clubface alignment and the horizontal clubhead path, favoring the former. The actual number varies with friction. In fact, it is solely friction which causes the ball to leave the face at any angle other than 90*. That's true vertically as well as horizontally. But none of this is new, as it was well documented in "Search For The Perfect Swing", which came out in 1968, one year before Homer's first edition.
