Interpretation
Scott (SCR-DR) started at 8:52 AM; David (P-DR) started at 8:42 AM. That gave David a 10 minutes head start on Scott. On foot, Scott ran 1:12:53 and David ran 1:22:46 — Scott was 9:53 faster than David. Scott took official place 719th (time-based 418th) and David took official place 716th (time-based 733rd).
