Wildbillmckinney,

"This third direction is the direction of the compressing force. The momentum of the violent return flow after impact also distorts the ball by exceeding the the normal dimension of the compressed point." Compressed Point here. Page 13 TGM.

So the bullet hole throught the baseball deals with force vectors. Page 17 2-c-1 #2B. Take this picture and turn it upside down. Now take a pencil and draw from compression point on the first ball to the next. There lies the angle of approach. You can also visualize the "curved blur" of the arc of approach. You can also see the LINE OF COMpression.

By the way- that tour player that was mixing arm only and shoulder only stroke---He was Danny Ellis. So THE Golfing Machine is definitely making a impact on tour.
