Interpretation

Dave (J-INV) started at 8:10 AM; Emily (P-DR) started at 8:42 AM. That gave Dave a 32 minutes head start on Emily because the Runner wave starts 27 minutes after the Invitational wave. On foot, Dave ran 1:34:42 and Emily ran 1:03:00 — Emily was 31:42 faster than Dave. Dave took official place 520th (time-based 1001st) and Emily took official place 523rd (time-based 135th). Dave's head start was enough to flip the official order even though Emily was faster on foot. Biggest swing: Emily gained 13:40 from Muir Woods to Cardiac.
