Interpretation
Olivia (Q-INV) started at 8:16 AM; Todd (N-INV) started at 8:14 AM. That gave Todd a 2 minutes head start on Olivia. On foot, Olivia ran 1:16:05 and Todd ran 1:17:49 — Olivia was 1:44 faster than Todd. Olivia took official place 357th (time-based 524th) and Todd took official place 353rd (time-based 577th). Todd's head start was enough to flip the official order even though Olivia was faster on foot. Biggest swing: Olivia gained 0:51 from Muir Woods to Cardiac.
