Bob,
We used to have a Sunday late afternoon group that played 9 holes with a modified stableford. Depending on the week there were anywhere from 4 to 20 guys. It was a great way for those of us with family duties to get out on the course for a little match on the weekend.
Everyone was assigned an initial budget based on our point system (1 pt. bogey, 2 pt. par, 3 pt. birdie, etc...0 pts. for doubles or worse) and that budget fluctuated up or down each week whether you exceeded your budget or came up short. The winner was whoever exceeded their total by the most points. You were never quite sure what that winning margin would be. It usually took at least a 3 point cushion, but I saw as little as +1 win and as much as +8. $5/man, winner takes the pot.
It was great fun and a way for a wide range of abilities to have a match. There was no small subset that seemed to win more than others. Most of the guys had some success now and again. The hardest part was establishing an initial budget for newcomers. Initial budgets were usually set at the high end of the player's ability and over time they would become more accurate. Everyone had to go through that adjustment phase, but it was still a lot of fun.
Unfortunately, several of the mainstays moved and others acquired a permanent tee time on Sunday mornings and the game kind of fell apart. It is a shame because it was great fun and I'd love to eventually be a part of a similar group...
