Interpretation
Becca (P-DR) started at 8:42 AM; Michael (U-DR) started at 8:46 AM. That gave Becca a 4 minutes head start on Michael. On foot, Becca ran 1:20:42 and Michael ran 1:16:58 — Michael was 3:44 faster than Becca. Becca took official place 678th (time-based 667th) and Michael took official place 682nd (time-based 552nd). Becca's head start was enough to flip the official order even though Michael was faster on foot. Biggest swing: Michael gained 1:25 from Cardiac to White Gate.
