Win rate by league and MMR
Grouped by the opponent's league and MMR band. Bands without enough games are left out.
How to read these numbers
- Green: the whole likely range is above 50%
- Too close to call
- Red: the whole likely range is below 50%
Likely range: We're 95% sure the true win rate is inside this range. Fewer games means a wider range.
Openers are ranked by the low end of the range, so a few lucky games can't top the table.
A number appears once at least 5 players have played 30 games in it; a guide page needs 100 games.
Compared with a snapshot at least 7 days old; moves under 0.5 pp count as flat.

Key timings
These timings come from 40 recorded build orders by 3 players. Buildings are timed when construction starts, upgrades and morphs when they finish, exactly as the replay records them. The median player finishes Metabolic Boost at 3:04, with the middle half between 3:01 and 3:10. Timing data is still thin (n = 40 replays), so expect these medians to move.
