EDITORIAL NOTE

Warhammer 40,000 11th edition launches Saturday 20 June 2026. The Archive is pausing weekly data ingestion (Performance pulls, ELO updates, Attention snapshots) through the transition and resuming with the first post-launch competitive weekend. Existing W23 data remains visible on every signal; the next data cycle lands the week of 3 July 2026, capturing tournaments held on 27–28 June — the first competitive weekend of 11th edition play. The Editor is using the gap for site refinements.

WILSON INTERVAL

CI EXPLORER

How wide is the uncertainty around that win rate?

A reported win rate is a measurement, not the true rate. The Wilson interval gives the range of values that are consistent with the data at a stated confidence level. The tighter the range, the more the sample supports the point estimate. Slide the controls below to explore.

WHY WILSON RATHER THAN WALD?

Wilson behaves well at small N and at proportions near 0 or 1, where the more familiar Wald (normal-approximation) interval becomes misleading. 95% is the conventional confidence level; this tool uses it throughout.
