Interpretation
James (P-DR) started at 8:42 AM; David (M-INV) started at 8:13 AM. That gave David a 29 minutes head start on James because the Runner wave starts 27 minutes after the Invitational wave. On foot, James ran 1:02:45 and David ran 1:31:14 — James was 28:29 faster than David. James took official place 521st (time-based 129th) and David took official place 516th (time-based 931st). David's head start was enough to flip the official order even though James was faster on foot. Biggest swing: James gained 10:42 from Muir Woods to Cardiac.
