Interpretation
Zoe (Q-DR) started at 8:43 AM; Jack (V-DR) started at 8:47 AM. That gave Zoe a 4 minutes head start on Jack. On foot, Zoe ran 1:22:37 and Jack ran 1:18:43 — Jack was 3:54 faster than Zoe. Zoe took official place 729th (time-based 723rd) and Jack took official place 731st (time-based 603rd). Zoe's head start was enough to flip the official order even though Jack was faster on foot.
