ELO Rating
extratime uses a modified ELO rating system to rank teams within each server.
How it works
Every team starts at 1000 ELO. After a match is recorded, both teams’ ratings are adjusted:
- Winner gains points
- Loser loses points
The number of points exchanged depends on the expected outcome based on the rating difference.
The expected score for Team A against Team B:
The new rating after a match:
Where:
K = 32 (the K-factor, controlling volatility)S = 1 for a win, 0 for a lossE = expected score
Examples
Key details
- ELO is per-server — a team’s rating in one server is independent of others
- ELO is team-based — individual players don’t have a separate ELO (the team’s roster determines its rating)
- Leaderboards sort by ELO descending
- ELO history is tracked and visible on team profiles
