This graph shows how far ahead or behind our schedule we were at each point in the trip. The schedule predicted a 24-hour ride, so we had a 70-minute buffer between our scheduled time and the record time. So when we hit 40 minutes behind schedule less than halfway into the trip, we didn't think we had much of a shot. Fortunately some good luck late at night, combined with insane sprints through several stations, allowed us to make all that time back.
