How Allston Street to Chestnut Hill Avenue was measured
The Allston Street to Chestnut Hill Avenue estimate uses 3,425 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.
