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.
