Interpretation
William (P-INV) started at 8:15 AM; Geoff (M-INV) started at 8:13 AM. That gave Geoff a 2 minutes head start on William. On foot, William ran 1:19:37 and Geoff ran 1:21:24 — William was 1:47 faster than Geoff. William took official place 431st (time-based 639th) and Geoff took official place 427th (time-based 690th). Geoff's head start was enough to flip the official order even though William was faster on foot. Biggest swing: William gained 2:01 from Muir Woods to Cardiac.
