You are absolutley correct. My theory is that this occurs because the ball is on the fringe and the shot is very much above the hole. The system (WGT) probably counters
this condition by slowing the ball down too much since any ball in the fringe will
be slowed down a bit before it hits the green. In this case (KIA #13) they clearly
(in my opinion) have overcompensated...I never putt from the fringe when its severe
downhill.
