How rating works

How the rating works

Only 4v4 matches count. The math is inspired by the official 4v4 ladder, not the official formula itself.

1. Starting rating

Everyone starts at 1000; the floor is 100.

2. Expected score

Each player is compared against the opponent team's average rating:

E = 1 / (1 + 10^((opponent team average − your rating) / 400))

3. Rating change

Win:  new = old + K × (1 − E)
Loss: new = old + K × (0 − E)

3.5 Why each player vs the opponent average

Applying 1v1 Elo to 4v4 naively means comparing team averages, which gives all four players identical deltas — a carry and a passenger would change by the same amount. The official 4v4 ladder compares each player's own rating with the opposing team, so a strong player gains little against a weak team, and a weak player loses little against a strong one. This site follows the latter.

4. K factor (per player, by games played)

5. Differences from the official ladder

• The official ladder only rates official queues; custom scenarios never get a rating. This site is a rating layer built for this map.
• One single ladder — no separation of 1v1 / team / Empire Wars.
• The official ladder shows "unranked" for the first 10 games; here a higher K simulates that.
• Disconnects count as losses.

6. Identity

Players are keyed by their Steam64 numeric ID, so renaming does not split a record.
