Interpretation
Josh (Y-DR) started at 8:50 AM; Robert (X-DR) started at 8:49 AM. That gave Robert a 1 minute head start on Josh. On foot, Josh ran 1:23:28 and Robert ran 1:24:13 — Josh was 0:45 faster than Robert. Josh took official place 917th (time-based 755th) and Robert took official place 913th (time-based 776th). Robert's head start was enough to flip the official order even though Josh was faster on foot. Biggest swing: Robert gained 1:16 from Muir Woods to Cardiac.
