Interpretation
Brian (V-INV) started at 8:20 AM; Eric (R-INV) started at 8:17 AM. That gave Eric a 3 minutes head start on Brian. On foot, Brian ran 1:10:44 and Eric ran 1:13:39 — Brian was 2:55 faster than Eric. Brian took official place 306th (time-based 348th) and Eric took official place 303rd (time-based 439th). Eric's head start was enough to flip the official order even though Brian was faster on foot. Biggest swing: Brian gained 1:06 from Windy Gap to Muir Woods.
