Interpretation
Susan (J-DR) started at 8:37 AM; Evan (W-DR) started at 8:48 AM. That gave Susan a 11 minutes head start on Evan. On foot, Susan ran 1:49:55 and Evan ran 1:39:10 — Evan was 10:45 faster than Susan. Susan took official place 1190th (time-based 1226th) and Evan took official place 1193rd (time-based 1081st). Susan's head start was enough to flip the official order even though Evan was faster on foot. Biggest swing: Evan gained 4:45 from Muir Woods to Cardiac.
