Interpretation
Alex (Y-DR) started at 8:50 AM; Jeff (U-DR) started at 8:46 AM. That gave Jeff a 4 minutes head start on Alex. On foot, Alex ran 1:09:44 and Jeff ran 1:13:15 — Alex was 3:31 faster than Jeff. Alex took official place 633rd (time-based 314th) and Jeff took official place 628th (time-based 430th). Jeff's head start was enough to flip the official order even though Alex was faster on foot.
