Interpretation
Koji (N-DR) started at 8:41 AM; Eric (Z-DR) started at 8:51 AM. That gave Koji a 10 minutes head start on Eric. On foot, Koji ran 1:19:49 and Eric ran 1:10:01 — Eric was 9:48 faster than Koji. Koji took official place 653rd (time-based 646th) and Eric took official place 657th (time-based 323rd). Koji's head start was enough to flip the official order even though Eric was faster on foot.
