Interpretation
John (W-INV) started at 8:21 AM; James (P-DR) started at 8:42 AM. That gave John a 21 minutes head start on James because the Runner wave starts 27 minutes after the Invitational wave. On foot, John ran 1:23:17 and James ran 1:02:45 — James was 20:32 faster than John. John took official place 517th (time-based 749th) and James took official place 521st (time-based 129th). John's head start was enough to flip the official order even though James was faster on foot. Biggest swing: James gained 11:16 from Muir Woods to Cardiac.
