Interpretation
Jason (V-DR) started at 8:47 AM; Pam (AAA-DR) started at 8:27 AM. That gave Pam a 20 minutes head start on Jason. On foot, Jason ran 1:21:08 and Pam ran 1:41:05 — Jason was 19:57 faster than Pam. Jason took official place 790th (time-based 681st) and Pam took official place 789th (time-based 1113th). Pam's head start was enough to flip the official order even though Jason was faster on foot. Biggest swing: Jason gained 5:04 from Muir Woods to Cardiac.
