Interpretation
Peter (Y-DR) started at 8:50 AM; Mattias (Q-DR) started at 8:43 AM. That gave Mattias a 7 minutes head start on Peter. On foot, Peter ran 1:19:20 and Mattias ran 1:26:19 — Peter was 6:59 faster than Mattias. Peter took official place 814th (time-based 626th) and Mattias took official place 813th (time-based 820th). Mattias's head start was enough to flip the official order even though Peter was faster on foot. Biggest swing: Peter gained 3:49 from Muir Woods to Cardiac.
