Interpretation
Kevin (P-INV) started at 8:15 AM; Mark (Q-INV) started at 8:16 AM. That gave Kevin a 1 minute head start on Mark. On foot, Kevin ran 1:06:36 and Mark ran 1:05:42 — Mark was 0:54 faster than Kevin. Kevin took official place 72nd (time-based 220th) and Mark took official place 76th (time-based 199th). Kevin's head start was enough to flip the official order even though Mark was faster on foot.
