Interpretation
Thor (Q-INV) started at 8:16 AM; David (Y-INV) started at 8:23 AM. That gave Thor a 7 minutes head start on David. On foot, Thor ran 1:07:56 and David ran 1:00:58 — David was 6:58 faster than Thor. Thor took official place 124th (time-based 259th) and David took official place 127th (time-based 77th). Thor's head start was enough to flip the official order even though David was faster on foot.
