Measurement Dynamics

Average WSI per country across measurement snapshots, rescored under rubric wsi-2026-v2. Nov 2024 scanned the top 1k origins in six countries; later measurements scanned the top 10k for Romania and Moldova. In the top-1k view, values for 10k measurements are the CrUX rank ≤ 1k subset extracted from the same scans — the same population definition as a native top-1k measurement.

Category BreakdownThe dashed line is the origin-weighted mean: Σ(category WSI × origins) / Σ(origins). Categories differ hugely in size (from a few hundred to several thousand sites), so a plain average of the eight category numbers would let a tiny category count as much as a huge one and misstate the regional level. Weighting by origin count makes each category count in proportion to its sites, so the line equals the true average WSI across every individual origin.
