I checked that, ChrisCrosby. For BPB, front 9 = 38.3, back 9 = 38.3, total = 76.6, with a slope of 144.
I personally have a 71.67 average at this time, which is .67 above BPB par. So I could round that up to a 0.7 handicap and figure out the course handicap, which is 1.0 for me.
For Kiawah, front 9 =36.6, back 9 = 36.8, total = 73.4, with a slope of 139. My average is .33 below Kiawah par, so, rounding to a .3 handicap, my Kiawah course handicap would be 0.
What I'd have to do is figure out the average of just rounds played on that course. That could be done for players with averages above 68.50 for Kiawah and 67.50 for Bethpage, because the USGA calculator only takes players with handicaps between +3.5 and 36.4.
I'll give you another example, with my good friend EllisSpice being used. (This includes tournaments.) His course handicap for nine holes at Bethpage Black is 6, and for 18, it's 15. I decided to pro-rate it for 18 holes being more accurate by adding 18-hole CH * 1.5. So the equation is [9CH + 18CH + (18CH*1.5)] / 2. For EllisSpice, his course handicap for BPB is 14.3. For Kiawah, [5 + 3 + (3*1.5)] / 2 = 6.25.
I can use this as well for the ranking system. I'm working on it guys! Hold out hope.
