Rankings - fascinating discovery

[eigs]

I was idly looking thru the pairs rankings when it struck me that the stats to level ratio was not simply a win-loss ratio. For instance Havoc28 has a 20 - 25 record and is level 6, Hardboiled has a 28 - 20 record and is level 5. This is just a for instance of stacks like that. Since clearly levels are not worked out according to games won and lost, does anyone know how they are evaluated because now I am truly intrigued. I have not looked at singles ratings but will do so just now, the whole thing has me fascinated! I cannot find any statistical thread and I am a mathematician (which I suppose it really has me most intrigued). Who could I even find out from I wonder?

Your sort of right there, the game does work on a win to loss ratio but once you get up to a level you cant move down to the level below, even if your win to loss ratio does go down. (I think).

OK guys come on help out here you stats guys - last night I (JuliaE and yes I am female) played really rubbish, let my partner down like a level 1 player and we lost - 12 - 13 record and stayed level 5. Now tonight I mesh well with partner, we play well and win, hence 13 - 13, all of a sudden I see I have been pushed to level 6 !!!!!!!! There are level 4 and 5 players with better win - loss ratios than that so this ranking definitely not depend on win/loss ratios, they are taking into account score anaysis or something. I WANT TO KNOW!!!!
