All this talk about Avatar movements, scales, overlays.......... bull they get you close but I believe it's all about the way the program is running at that time of the day.
They say math doesn't lie, so if you figure out the the yardage for each movement for that club, the ball should come close to that figure.( + - 2-3 feet )
Some days your right on, same day same course way the heck off go figure. Didn't change the way I play the hole, formula didn't change, clubs didn't change, so what had to change the way the program was reading the shots. IMO
