Interpretation
Johan (X-DR) started at 8:49 AM; Jonnie (L-DR) started at 8:39 AM. That gave Jonnie a 10 minutes head start on Johan. On foot, Johan ran 1:36:16 and Jonnie ran 1:46:00 — Johan was 9:44 faster than Jonnie. Johan took official place 1162nd (time-based 1037th) and Jonnie took official place 1158th (time-based 1179th). Jonnie's head start was enough to flip the official order even though Johan was faster on foot. Biggest swing: Johan gained 2:26 from Muir Woods to Cardiac.
