Example: 1648 http://fr.boardgamearena.com/theme/img/common/rank.png.

If you never play a game on BGA, your initial rating is 1500 . Each time you win a game your rating increases, and it decreases each time you loose a game.

In case there are more than 2 players at the table, we take into account the final rank. This is the reason it is important to continue fighting for the second place during the game if you think you can't win.

== Okay, but I want to know the formula ! ==

At first, when someone left a game for any reason this game is not taken into account by the ELO rating system.

* Table Level (TL) is the average of ELO ratings of all players at this table.
* The success (S) of a player depends directly on its ranking at the game, from S=+470 (winner of the game) to S=-470 (last player).
* The performance (P) of a player is TL+S.
* The new ELO rating (Rn) is a weighted average of the previous ELO rating (Rp) and the performance: Rn = K.P + (1-K).Rp

== Good players, Experts, Masters ==

* Good players: > 1600 ELO
* Experts: > 1800 ELO
* Masters: > 2000 ELO
