Interpretation
Emily (P-DR) started at 8:42 AM; Hector (Y-INV) started at 8:23 AM. That gave Hector a 19 minutes head start on Emily because the Runner wave starts 27 minutes after the Invitational wave. On foot, Emily ran 1:03:00 and Hector ran 1:21:45 — Emily was 18:45 faster than Hector. Emily took official place 523rd (time-based 135th) and Hector took official place 522nd (time-based 700th). Hector's head start was enough to flip the official order even though Emily was faster on foot. Biggest swing: Emily gained 8:22 from Muir Woods to Cardiac.
