Hi,
I'd like to share a new ranking proposal based on the classical poker pay-out, a zero sum system.
It's a KISS model which does not need any penalty factor because it's a sum, not an average score.
It can seem a bit cruel, but poker is cruel. That's why we all must learn, learn how to win and, maybe more important, learn how not to loose too much and still have fun.
First, the score can be a positive or a negative number. It represents the "money" you would have won or lost. A kind of return on investment (ROI).
The system ( note that i talk about 10 players games):
1) playing a game cost one point (-1): it represents the "buy-in" and create the amount to win (the pot), usually 10 points.
2) at the end of the game, the "pay-out":
the 1st takes 6.5 points out of 10 in the pot, so he/she wins +5.5 (6.5 - the buy in)
2nd takes 2.5 points (so +1.5)
3rd takes 1 point that just covers the buy in, his/her money back (so +0 score)
others (4th to 10th) loose one point (so -1)
and that's all.
High scores like 100 or more are only reachable by a huge number of games, something like 70 games for best players... Low skills players won't never reach such a score 'cause it will drop by the time...
New account with less than 30 games can't reach high score, +30/+40 at best...
For best understanding I give you some exemples:

-200 in 226 games, so an Average Profit (AP) -0.8850

-24.5 in 54 games, so AP= -0.4537

+3.5 in 12 games so AP= +0.2917

+5.5 in 11 games so AP= +0.5

+38 in 28 games so AP= +1.3571

+109 in 99 games so AP= +1.101

+92.5 in 94 games so AP= +0.9840

+74.5 in 85 games so AP= +0.8765
http://www.poker-heroes.com/profile.html?user=jeanflush
+28 in 59 games so AP= +0.4746
Someone who played 30 games and score +30 is very good players 'cause he/she makes and average profit of 1 (he/she pays 1 to win 2, which make 1 profit): we can say that he/she plays in a profitable way, that means that he/she deserves a top ranking place...Simple.
A good contest could be: to reach a 100+ score with the lesser number of games. Or the same with a 200 score.
What do you think about this system?
Good, bad or something to adjust?

edit 5 december: boehmi told me that not to favour hardcore players vs occasional ones we must calculate the "average profit" (the score in my system is the "profit", we just have to divide it by the number of games) and then apply a penalty factor under 30, 50 or "n" games. This "average profit" is the final ranking score. I also edited the average profit in the exemple above.
