Interpretation
Eliu (U-INV) started at 8:19 AM; Sean (Y-INV) started at 8:23 AM. That gave Eliu a 4 minutes head start on Sean. On foot, Eliu ran 1:10:00 and Sean ran 1:06:00 — Sean was 4:00 faster than Eliu. Eliu took official place 255th (time-based 321st) and Sean took official place 257th (time-based 207th). Eliu's head start was enough to flip the official order even though Sean was faster on foot. Biggest swing: Sean gained 2:21 from Muir Woods to Cardiac.
