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.

METHODOLOGY

PROTOCOL

How the Archive shows its work.

Most win-rate tables are verdicts. Protocol is the part that comes before the verdict — the question of whether the verdict can be trusted in the first place. Sample size, confidence intervals, the difference between a real shift and a coin flip in a small dataset. The Archive’s stance is that methodology should not be hidden behind the answer; it should be the answer’s foreground.

A speculative column on a hypothetical 11th-edition cover-rules change — what one drafting decision could do to the opening months of the new edition. Editor voice; in dialogue with the methodology pieces above without being one.

The Cover Ledger
The companion to Where Cover Lives. Does the full durability accounting of the new cover rule, archetype by archetype and weapon by weapon — and finds that −1 BS is not the universal upgrade it can look like.

All Phase 2 methodology tools are live, plus the five methodology articles — see the Methodology Library. The four explainers (Big Soup, Six Bins, Swiss Isn’t Random, On Average) sit alongside the Editor’s methodology editorial What the Numbers Can Bear, which makes the case for what the four taken together actually argue. The Editor’s feature long-reads sit one register over — speculative analysis distinct from the methodology explainers. The pair so far: Where Cover Lives, the structural argument that the cover rule’s move from save-roll to hit-roll opens a stacking problem, and its companion The Cover Ledger, the durability accounting that shows where the rule actually lands.
