Interpretation
Jaclyn (M-INV) started at 8:13 AM; Andrew (V-INV) started at 8:20 AM. That gave Jaclyn a 7 minutes head start on Andrew. On foot, Jaclyn ran 1:18:24 and Andrew ran 1:11:34 — Andrew was 6:50 faster than Jaclyn. Jaclyn took official place 338th (time-based 590th) and Andrew took official place 343rd (time-based 374th). Jaclyn's head start was enough to flip the official order even though Andrew was faster on foot. Biggest swing: Andrew gained 3:00 from Muir Woods to Cardiac.
