NikolajK: Basicly You're telling me to add 33% on fast greens. Is that correct and how many types of greens are there?
Yes, that's what I did. 6 becomes 8 9 becomes 12, etc. I think there's 4 or 5 but you'll see the difference when you use those values in your post on fast or very fast greens. Everything will be coming up short. Use separate values for each green speed.
The best way to get a handle of what works for you is to set up a practice round at BPB, back 9. Red tees, no wind, slow greens. The 10th and 11th greens there are huge and relatively flat. Get on in 2 and you'll have 8 putts before you're maxed out. Putt back and forth to get your feel and distances down. Don't worry about break until you master the distance-the 2 go hand in hand but the correct distance on your putts is what will get them in the hole. After 11 you can restart and get another 16 putts in a short amount of time. Set the next round to fast greens and do the same thing. You get the idea.
It's a bit tedious but extremely beneficial because your putting is almost 50% of your game. :-)
