Interpretation
Hector (Y-INV) started at 8:23 AM; Dave (J-INV) started at 8:10 AM. That gave Dave a 13 minutes head start on Hector. On foot, Hector ran 1:21:45 and Dave ran 1:34:42 — Hector was 12:57 faster than Dave. Hector took official place 522nd (time-based 700th) and Dave took official place 520th (time-based 1001st). Dave's head start was enough to flip the official order even though Hector was faster on foot. Biggest swing: Hector gained 5:18 from Muir Woods to Cardiac.
