Category BreakdownThe dashed line is the origin-weighted mean: Σ(category WSI × sites) / Σ(sites). Categories differ hugely in size, so a plain average of the category numbers would let a tiny category count as much as a huge one. Weighting by site count makes each category count in proportion to its origins, so the line equals this country's average WSI across every individual site.

Performance contextFor each eligible origin, LCP p75 is the primary perceived-performance metric and TTFB p75 is a secondary delivery control. COUNTRY records come from the CrUX BigQuery country dataset. CrUX API records are GLOBAL even when the origin belongs to this country's cohort. Country cards show the mean across origin-level p75 values, not a recomputed country-wide user percentile. These contextual metrics never contribute to WSI.
