Hi Bill,
Since the course's slope rating and course rating is not displayed here on WGT, determining a player's handicap (or playing potential) would be difficult. If you play real golf and are a member of the USGA or R&A, you probably know how one's handicap is determined.
Since WGT keeps a players average based on their current tier and does not maintain a handicap for each player, it would be extremely difficult to determine each player's "playing potential". First you would need to know the course rating for each of the courses on WGT. Next, you would need to know the slope rating from the tee's. You would then need to determine the player's adjusted score, then calculate the differential using the following calculation:
Handicap Differential = (Adjusted Gross Score - Course Rating) x 113 / Slope Rating
This would need to be done for the last 20 scores posted by each player in the tournament. Afterward, you would pick the lowest 10 handicap differentials and determine the average. Taking this average and multiplying it by .96 would give you the player's handicap index.
Now, you would take this index and calculate the course's handicap for the player as follows:
(Player's Handicap Index X Course's slope rating from their designated tee box) / 113 = player's course handicap for said course. (rounded to a whole number)
Each course has their own course rating and each tee on the course has a designated slope rating.
Now if you wish to calculate the handicaps for each player, forgoing adjusted scores and using just the player's scores, having a handicap tournament would be quite a bit of fun! If you're willing to do the handicapping for each player, count me in! Sounds like a lot of fun (but a lot of work).
