How Chestnut Hill Avenue to Chiswick Road was measured
The Chestnut Hill Avenue to Chiswick Road estimate uses 178 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.
