WHAT DO THE FACET Z-SCORES MEAN?

Each facet number below is a z-score — a comparison to the whole competitive roster this window. Zero is the roster average; +1.0 is one standard deviation above (roughly the top 16% of factions on that facet), +2.0 is exceptional; the scale mirrors going down. The four facets — win rate, top-cut conversion, blowout margin, consistency — combine into the Strength Index composite, weighted on the tier-list page. Top players is a comparison layer: the curated top-player tier list, shown beside the results but never blended into the composite.

WHAT THE WINNING LISTS RUN UNITS IN THIS FACTION’S UNDEFEATED & ONE-LOSS ARMIES · 2026-W27

Across the 7 Chaos Space Marines armies that went undefeated or one-loss this window, ranked by how often each unit appears. Faction-anonymous — the lists are counted, never attributed to a pilot.

“Winning” here means the pilot finished undefeated (X–0) or one-loss (X–1) at a 5+ round singles event with a field of 16 or more. Share is the fraction of those 7 lists that included the unit; a datasheet run in multiples still counts as one list. No rules or profile text — unit names and counts only.
