Interpretation
Emma (Q-DR) started at 8:43 AM; Eric (AAA-INV) started at 8:00 AM. That gave Eric a 43 minutes head start on Emma because the Runner wave starts 27 minutes after the Invitational wave. On foot, Emma ran 1:01:21 and Eric ran 1:44:05 — Emma was 42:44 faster than Eric. Emma took official place 518th (time-based 91st) and Eric took official place 515th (time-based 1156th). Eric's head start was enough to flip the official order even though Emma was faster on foot. Biggest swing: Emma gained 16:01 from Muir Woods to Cardiac.
