Acela delay questions

How do you measure Acela delays?
We record the delay at the final stop of each trip that completed, from Amtrak's live data. Cancelled trips are not counted. A trip is on time when it arrives 5 minutes late or less. Amtrak counts a trip as on time at 10 to 15 minutes depending on the route, so its figures can differ from ours; the 'within 10 minutes' share is the closest to Amtrak's threshold.
