Back in Texas, my old league worked like this:
$5 to enter the league. A win was 8 points. A loss was 2 points. A draw was 5.
Playing a new opponent (can only be gotten once per opponent) was 1 point
Playing each week (no added up bonuses. playing 8 out of 8 weeks is 8 total points. playing only 1 week is 1 point) was 1 point.
Each game you played was $1. You can work it out with your opponent as to who pays. Usually, the loser paid.
You could only play 3 matches a week max.
Point values can range from 750-2500.
This system kept money flowing, the game enjoyable, and fair to not make people get so far ahead in points, but favorable to play more games.
