Interpretation
Nathan (N-DR) started at 8:41 AM; Lily (M-DR) started at 8:40 AM. That gave Lily a 1 minute head start on Nathan. On foot, Nathan ran 1:28:05 and Lily ran 1:29:00 — Nathan was 0:55 faster than Lily. Nathan took official place 809th (time-based 867th) and Lily took official place 808th (time-based 886th). Lily's head start was enough to flip the official order even though Nathan was faster on foot. Biggest swing: Lily gained 1:23 from Cardiac to White Gate.
