 Bertrand's Alternative Scoring System 
Long term
Week of 20080330
Week of 20080406
Week of 20080413
A zerosum system calculated like this:
New score = Previous score + Base score + Skill score
Base score:
1: +10
2: 2
3: 2
4: 2
5: 2
6: 2
NOTE: the base score is halved if the spread between the winner and the average of the other players is greater than 20, and eliminated if the spread is greater than 30. This is to prevent good players from boosting their score by exploiting beginners and bots.
Skill score:
Add 1 for each opponent that you beat and has a higher or equal score than you.
Subtract 1 for each opponent that beat you and has a lesser or equal score than you.

 Raw Pot: Winner Takes All 
In this scoring system, all players contribute to a raw pot at the start of the game. To be precise, 4% of each players raw goes into the pot. At the end of the game, the winner gets all the raw in the pot, and the losers lose the 4% that they put in.
The 4% value can be changed, and different values will give different results.
