Interpretation
BJ (Y-DR) started at 8:50 AM; Bjorn (U-DR) started at 8:46 AM. That gave Bjorn a 4 minutes head start on BJ. On foot, BJ ran 1:25:46 and Bjorn ran 1:29:38 — BJ was 3:52 faster than Bjorn. BJ took official place 976th (time-based 806th) and Bjorn took official place 972nd (time-based 902nd). Bjorn's head start was enough to flip the official order even though BJ was faster on foot.
