MEASUREMENT SAMPLE

How Chiswick Road to Arlington was measured

The Chiswick Road to Arlington estimate uses 3,306 completed direct-trip stop-timestamp pairs matched to the schedule active for each observed train.

We publish the median because one dramatic delay should not define an everyday journey, and the 90th percentile because riders still need to understand the bad end of normal.

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