pdb1: They are exactly 6 ft increments .
Not what I found when I was on the practice green mapping my Sabretooth. At the easy green, champ speed and the first movement (20% on pp) the ball rolls 8.4 feet. Second movement (40 % on pp) 19 feet and so on. I hit 12 putts at each increment, only counted dings, and then averaged them to get my numbers.
Thanks for the response but I like to actually hit the ball at the different increments to see just how far they roll. I use to use St Andy's #1 easy flag and from the left of the green you have a nice level area...
