## Methodology

Latest full provider RTT extract for active London trusts. Weekly wait columns are collapsed into six published-duration bands; pathways with an unknown clock start remain a separate segment rather than being forced into a duration. Counts are pathways rather than unique patients, and describe providers rather than London residents.
