Interpretation
Shelby (L-DR) started at 8:39 AM; James (Y-DR) started at 8:50 AM. That gave Shelby a 11 minutes head start on James. On foot, Shelby ran 1:40:29 and James ran 1:29:35 — James was 10:54 faster than Shelby. Shelby took official place 1069th (time-based 1101st) and James took official place 1071st (time-based 898th). Shelby's head start was enough to flip the official order even though James was faster on foot. Biggest swing: James gained 3:59 from Muir Woods to Cardiac.
