How can i calculate the roll out after landing on the green ????
As far as i know there is no way to calculate the roll out on the green.There are just too many factors to take into consideration. Downslope upslope green speed to name a few, Is the green one of those where the ball rolls forever like 2,5,13. and 14 at St.Andrews.
It is just an educated guess
