Interpretation
Dave (AAA-INV) started at 8:00 AM; John (N-DR) started at 8:41 AM. That gave Dave a 41 minutes head start on John because the Runner wave starts 27 minutes after the Invitational wave. On foot, Dave ran 1:56:44 and John ran 1:16:19 — John was 40:25 faster than Dave. Dave took official place 596th (time-based 1270th) and John took official place 601st (time-based 530th). Dave's head start was enough to flip the official order even though John was faster on foot. Biggest swing: John gained 13:17 from Muir Woods to Cardiac.
