Interpretation
Scott (A-INV) started at 8:02 AM; Dan (W-INV) started at 8:21 AM. That gave Scott a 19 minutes head start on Dan. On foot, Scott ran 1:27:30 and Dan ran 1:08:45 — Dan was 18:45 faster than Scott. Scott took official place 273rd (time-based 850th) and Dan took official place 278th (time-based 283rd). Scott's head start was enough to flip the official order even though Dan was faster on foot.
