I wanted to post another thing about that subject. ELO in LoL isn't as accurate as in chess by no mean. There are several reasons for that:

> 5on5 vs 1on1: You can get carried by someone else, get some good luck/bad luck (afk/leaver/play with someone at an unaccurate ELO -way up or way down like the new lvl 30 150 Wins trying ranked or the one that improved on normal before rejoining Ranked). I pretend that the law of average evens this effect, however, it's true that it affects your current ranking and make it less accurate than in chess.

e.g.: You are perfectly ranked. You play 10 games and some unluck makes you lose 8 instead of 5, you will have 50 ELO less than your true level. After some games you will be back there.

> Team mentality: you may be worser in skill than others but you may pick for the team instead of beeing a non-caring dumbass that simply picks his main. You win some games more even if your less skilled -gamewise- than careless players.

> Number of characters: That's another aspect that screw somewhat your ELO. If your best chars have been picked/banned, you may play a character which your less-skilled at. Actual competency < ELO value.

> Game balance: A bias exists too depending on the game balance. A player who picks Eve-Panth and what not may in thruth be better than the guy looking at OP characters despite what their ELO says.

> Duo-team in solo-Q can be the last bias thanks to the synergie.

However, these bias must have an effect of, well, 100? 200 (at max)? ELO. I can't say without data (it would requiere to analyse the average discrepency of ELO for the players over time.

This beeing said, chess ELO>LoL ELO, but LoL ELO= best classement system available.
