Interpretation
Eric (R-INV) started at 8:17 AM; Brian (V-INV) started at 8:20 AM. That gave Eric a 3 minutes head start on Brian. On foot, Eric ran 1:13:39 and Brian ran 1:10:44 — Brian was 2:55 faster than Eric. Eric took official place 303rd (time-based 439th) and Brian took official place 306th (time-based 348th). Eric's head start was enough to flip the official order even though Brian was faster on foot.
