About our Data

What is an ELO rating and how is it calculated?
An ELO rating is a way to evaluate the relative skill level of a player in any sport. It is commonly known for being used in chess. However, it has been used in more modern sports like the NBA and NFL (FiveThiryEight
Our ELO ratings are divided into two parts. First is the ELO rating based on placements (pELO). The second part is based on player statistics. We call them pELO (placing) and sELO (stats). To calculate a player's new pELO after a LAN tournament, we simulate the following matches: (This is an example for a 16+ team tournament with our defaukt K-value = 32):
- 1st: Win against 2000 ELO opponent
- 2nd: Win against 1900 ELO opponent
- 3rd: Win against 1800 ELO opponent
- 7th+: Loss against 2000 ELO opponent
- 12th+: Loss against 1900 ELO opponent
- 16th+: Loss against 1800 ELO opponent
To illustrate pELO in an example, let's look at Dashy. Going into CWL Vegas (Bo4) he had a pELO of 1231
. With a 1st place finish, we obtain Dashy's new pELO
by simulating a win against a 2000 ELO opponent. So his new pELO becomes 1263 (+32)
