Interpretation
David (Y-INV) started at 8:23 AM; Crispin (W-INV) started at 8:21 AM. That gave Crispin a 2 minutes head start on David. On foot, David ran 1:00:58 and Crispin ran 1:02:55 — David was 1:57 faster than Crispin. David took official place 127th (time-based 77th) and Crispin took official place 123rd (time-based 133rd). Crispin's head start was enough to flip the official order even though David was faster on foot. Biggest swing: David gained 0:34 from Muir Woods to Cardiac.
