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 111 recorded build orders by 6 players. Buildings are timed when construction starts, upgrades and morphs when they finish, exactly as the replay records them.
