Interpretation

Dave (J-INV) started at 8:10 AM; James (P-DR) started at 8:42 AM. That gave Dave a 32 minutes head start on James because the Runner wave starts 27 minutes after the Invitational wave. On foot, Dave ran 1:34:42 and James ran 1:02:45 — James was 31:57 faster than Dave. Dave took official place 520th (time-based 1001st) and James took official place 521st (time-based 129th). Dave's head start was enough to flip the official order even though James was faster on foot. Biggest swing: James gained 13:45 from Muir Woods to Cardiac.
