Look at 2-C-1 #2B, notice the Impact Point is not the back of the ball, but the inside aft quadrant. When the ball leaves the Club Face, however, at Separation it is at a different location and the club face is now at right angles to where the ball leaves it. Impact and seperation are at two different places, about 3/4 of an inch difference.
Notice in 2-C-1 #2B that the center line does not point down the flight line, it points to "right field", just as it does in 2-C-1 to take into account the closing motion between Impact and Seperation.
Go to 2-C-2 and notice because there is no closing of the Club Face, the Center Line for both Impact and Seperation are both straight lines.
Hope this helps.

Drewitgolf- On Fire!
First- where the hell is the "On-Fire" SMILIE!!!! Come on guys get this website up to speed!
Second, Be careful about the 3/4's of an inch- depends on what shot - how much compression- and even with a Driver- I'm not sure the center of gravity of the ball moves 3/4's of an inch- (But I love to see the evidence!
)
Nice work Drewitgolf!
