ELO rating?

I would like to know what ELO stands for, and what this rating is. I've tried to search around. It's a rating that determines match-ups I figure? Is it real competitive to be on the top 500 list on leaguecraft? I know there's a FAQ thread on it that I've seen posted, but nowhere do I see what ELO actually stands for.

Q: How does ELO work? What does it mean? Where can I see it?

A: ELO is the ranking system used in LoL. The way is works is that when you get matched up against a team, your team will be expected to win or expected to lose, depending on your ELO.


Team A - 1250 ELO Ranking
Team B - 1350 ELO Ranking

In this scenario, Team B is expected to win. If they win, they will gain less ELO because they were the stronger team going in.

Team A - 1250 -> 1242
Team B - 1350 -> 1358

However, should Team A win, they will gain more points than usual because it was an upset.

Team A - 1250 -> 1263
Team B - 1350 -> 1337

Note that this is acting as if the entire team has their own ELO, what actually happens is that a team's ELO is considered depending upon the players inside and other factors. As an example:

A pre-made comes in with these players:

Noob - 1000
N0ob - 1000
Noobie - 1000
Newbie - 1000
Newskis - 1000

Now, this team doesn't have a 1000 point rating when it gets put into the pool. What happens is that they get a slight modification (between 25 and 200 points, I think) because they are a premade, and are expected to be stronger than simple pubs. So, even though all the players are 1000 ranked, the actual team would probably be ranked 1100-1150.

There isn't any way to see your ELO ranking from Normal games. The idea there is that the matchmaking is for fun, and that you shouldn't be worried about losing. When Ranked games come in, those are where the ladders and competitive play will be shown.

Also look at this (http://www.leagueoflegends.com/board/showthread.php?t=12029) thread. Its a little outdated, but still very useful.

The Elo rating system is a method for calculating the relative skill levels of players in two-player games such as chess (http://en.wikipedia.org/wiki/Chess) and Go (http://en.wikipedia.org/wiki/Go_%28board_game%29). It is named after its creator Arpad Elo (http://en.wikipedia.org/wiki/Arpad_Elo), a Hungarian (http://en.wikipedia.org/wiki/Hungary)-born American (http://en.wikipedia.org/wiki/United_States) physics (http://en.wikipedia.org/wiki/Physics) professor..

So it's named after the dude who invented it who was named Elo.
