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 LTS cohort (330 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).

PerformanceTestRunInfo.json and PerformanceTestRunSettings.json are no longer generated during player builds that do not include test assemblies, as they are only read by performance tests running inside the player. Stale files left behind by an aborted test build are removed before such builds instead of being included in them.
