Tom,
It will be interesting to see what Davis says. It think it is unfortunately more complicated than we would hope it should be. As a quick example, if you take a course's #1 handicap hole and move the tees to the forward most position, is it still the #1 handicap hole? This makes a big difference if you are in a match play event and strokes are being allocated based on the hole handicaps. We spent a lot of time on all these issues and ended up with new cards/handicaps/ratings for the the new tee locations. Again, none of this matters too much if you are playing without handicaps as the pros do. However, if you do keep a handicap, you need to turn in a score along with a slope and course rating for the course you played. Maybe some else here who is more expert on the handicapping system than I will chime in?
