Interpretation
BJ (Y-DR) started at 8:50 AM; Tom (F-DR) started at 8:34 AM. That gave Tom a 16 minutes head start on BJ. On foot, BJ ran 1:25:46 and Tom ran 1:41:38 — BJ was 15:52 faster than Tom. BJ took official place 976th (time-based 806th) and Tom took official place 971st (time-based 1118th). Tom's head start was enough to flip the official order even though BJ was faster on foot.
