Interpretation
Amy (G-DR) started at 8:35 AM; Reed (Z-DR) started at 8:51 AM. That gave Amy a 16 minutes head start on Reed. On foot, Amy ran 1:38:34 and Reed ran 1:22:46 — Reed was 15:48 faster than Amy. Amy took official place 922nd (time-based 1075th) and Reed took official place 925th (time-based 731st). Amy's head start was enough to flip the official order even though Reed was faster on foot. Biggest swing: Reed gained 4:56 from Muir Woods to Cardiac.
