Interpretation
Christopher (U-INV) started at 8:19 AM; William (P-INV) started at 8:15 AM. That gave William a 4 minutes head start on Christopher. On foot, Christopher ran 1:15:42 and William ran 1:19:37 — Christopher was 3:55 faster than William. Christopher took official place 433rd (time-based 511th) and William took official place 431st (time-based 639th). William's head start was enough to flip the official order even though Christopher was faster on foot. Biggest swing: Christopher gained 2:01 from Muir Woods to Cardiac.
