How Hynes Convention Center to Saint Mary's Street was measured
The Hynes Convention Center to Saint Mary's Street estimate uses 3,524 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.
