Interpretation
Jason (V-DR) started at 8:47 AM; Pierce (Q-DR) started at 8:43 AM. That gave Pierce a 4 minutes head start on Jason. On foot, Jason ran 1:21:08 and Pierce ran 1:25:00 — Jason was 3:52 faster than Pierce. Jason took official place 790th (time-based 681st) and Pierce took official place 787th (time-based 792nd). Pierce's head start was enough to flip the official order even though Jason was faster on foot. Biggest swing: Jason gained 2:21 from Muir Woods to Cardiac.
