Replay-engine records only: two equal human teams of at least two players, known public keys, at least 3 minutes, no crash or cheat flag. One-on-one, incomplete, and excluded matches do not change this rating.

Each account starts at 1500. Pre-match team-average ratings set the expected win chance. Win = 1, draw = 0.5, loss = 0. Result points = K × (actual − expected), with K starting at 16 and tapering to 10 after 20 rated games.

Combat efficiency 45%, building pressure 25%, unit production 20%, research 10%. Counters are compared with earlier matches of similar team size and duration, preferring the same map when enough samples exist. Team shares produce a personal change capped at ±8.

Total change is capped at ±15 per match. If trusted counters or comparison samples are missing, that match uses team-result scoring only. A positive change after a loss is possible, but not guaranteed.
