Interpretation
Elton (V-INV) started at 8:20 AM; William (P-INV) started at 8:15 AM. That gave William a 5 minutes head start on Elton. On foot, Elton ran 1:14:45 and William ran 1:19:37 — Elton was 4:52 faster than William. Elton took official place 434th (time-based 469th) and William took official place 431st (time-based 639th). William's head start was enough to flip the official order even though Elton was faster on foot. Biggest swing: Elton gained 1:43 from Muir Woods to Cardiac.
