How this number is computed

Composite = sum of sub_score × weight across six metrics. Sub-scores are percentile-rank(log1p(min(raw, p95))) within the alpha cohort (41 releases). Sub-scores for lower-is-better metrics are flipped to 100 − percentile.

Sub-score	Formula	Raw	Clip	%ile	Weight	Score	Contrib

* = raw value was clipped at the cohort 95th percentile to prevent outliers from compressing everyone else's scores. Sub-scores marked "med" substitute the cohort median where the input was missing (e.g. first patch on a minor line has no prior patch for net-fix delta).

Fixed an issue where a Tilemap did not instantiate the GameObjects of its tiles on every other scene load or Play mode entry. (UUM-155958) Fixed in 7000.0.0a10.
