Interpretation
Ray (J-DR) started at 8:37 AM; Amy (G-DR) started at 8:35 AM. That gave Amy a 2 minutes head start on Ray. On foot, Ray ran 1:36:37 and Amy ran 1:38:34 — Ray was 1:57 faster than Amy. Ray took official place 923rd (time-based 1049th) and Amy took official place 922nd (time-based 1075th). Amy's head start was enough to flip the official order even though Ray was faster on foot. Biggest swing: Ray gained 3:40 from Muir Woods to Cardiac.
