Interpretation
Ben (P-DR) started at 8:42 AM; David (G-DR) started at 8:35 AM. That gave David a 7 minutes head start on Ben. On foot, Ben ran 1:51:36 and David ran 1:58:23 — Ben was 6:47 faster than David. Ben took official place 1254th (time-based 1239th) and David took official place 1252nd (time-based 1281st). David's head start was enough to flip the official order even though Ben was faster on foot. Biggest swing: Ben gained 4:37 from Muir Woods to Cardiac.
