Great info. so far guys. To answer some questions...When the orginal handicapping was done there was no water on the course. Now there is water on 7 holes. The state golf association has told us it is up to us. In the sample data all levels of play were used from all 4 sets of tees. And all levels of handicaps were used. When the course was built a committee of guys used very little data to come up with the handicaps. And there was virtually no water on the course to start with. The course is Cross Roads Golf Course in Carrington, ND. Quite simply, what made the data come up different now was the number of rounds used. (and the water) Lefty...You shed new light on the subject that I was hoping was out there. The original committee alternated holes front to back, but my understanding is that this isn't mandatory. (they did this based on there early score findings) I am going to do a little more work using what you say the USGA does. The problem with this method is that with the scoring data only, the top 6 most difficult holes are on the back. Doing what you are saying would make the 7th most difficult hole the #1 handicap hole just because it is on the front correct?
