Interpretation
Eric (AAA-INV) started at 8:00 AM; John (W-INV) started at 8:21 AM. That gave Eric a 21 minutes head start on John. On foot, Eric ran 1:44:05 and John ran 1:23:17 — John was 20:48 faster than Eric. Eric took official place 515th (time-based 1156th) and John took official place 517th (time-based 749th). Eric's head start was enough to flip the official order even though John was faster on foot. Biggest swing: John gained 5:10 from Cardiac to White Gate.
