How Chestnut Hill Avenue to Blandford Street was measured
The Chestnut Hill Avenue to Blandford Street estimate uses 3,326 completed direct-trip stop-timestamp pairs matched to the schedule active for each observed train.

We do not infer why a trip ran slowly. Construction, incidents, crowding and weather require separate evidence.
