Interpretation
Alex (X-INV) started at 8:22 AM; Tatem (M-INV) started at 8:13 AM. That gave Tatem a 9 minutes head start on Alex. On foot, Alex ran 1:06:46 and Tatem ran 1:15:44 — Alex was 8:58 faster than Tatem. Alex took official place 244th (time-based 223rd) and Tatem took official place 243rd (time-based 514th). Tatem's head start was enough to flip the official order even though Alex was faster on foot.
