How Chiswick Road to Griggs Street was measured
The Chiswick Road to Griggs Street estimate uses 3,374 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.
