Interpretation
Alice (Q-DR) started at 8:43 AM; Michael (X-DR) started at 8:49 AM. That gave Alice a 6 minutes head start on Michael. On foot, Alice ran 1:33:29 and Michael ran 1:27:34 — Michael was 5:55 faster than Alice. Alice took official place 999th (time-based 973rd) and Michael took official place 1000th (time-based 852nd). Alice's head start was enough to flip the official order even though Michael was faster on foot. Biggest swing: Michael gained 2:56 from Muir Woods to Cardiac.
