Interpretation
Amy (M-INV) started at 8:13 AM; Clara (P-INV) started at 8:15 AM. That gave Amy a 2 minutes head start on Clara. On foot, Amy ran 1:01:59 and Clara ran 1:00:00 — Clara was 1:59 faster than Amy. Amy took official place 11th (time-based 111th) and Clara took official place 12th (time-based 66th). Amy's head start was enough to flip the official order even though Clara was faster on foot. Biggest swing: Clara gained 1:52 from Muir Woods to Cardiac.
