Interpretation
Dave (J-INV) started at 8:10 AM; Nikko (T-DR) started at 8:45 AM. That gave Dave a 35 minutes head start on Nikko because the Runner wave starts 27 minutes after the Invitational wave. On foot, Dave ran 1:34:42 and Nikko ran 1:00:00 — Nikko was 34:42 faster than Dave. Dave took official place 520th (time-based 1001st) and Nikko took official place 524th (time-based 67th). Dave's head start was enough to flip the official order even though Nikko was faster on foot. Biggest swing: Nikko gained 14:31 from Muir Woods to Cardiac.
