Interpretation
Emma (Q-DR) started at 8:43 AM; John (W-INV) started at 8:21 AM. That gave John a 22 minutes head start on Emma because the Runner wave starts 27 minutes after the Invitational wave. On foot, Emma ran 1:01:21 and John ran 1:23:17 — Emma was 21:56 faster than John. Emma took official place 518th (time-based 91st) and John took official place 517th (time-based 749th). John's head start was enough to flip the official order even though Emma was faster on foot. Biggest swing: Emma gained 12:03 from Muir Woods to Cardiac.
