Interpretation
Sean (W-DR) started at 8:48 AM; Luke (L-DR) started at 8:39 AM. That gave Luke a 9 minutes head start on Sean. On foot, Sean ran 1:37:47 and Luke ran 1:46:35 — Sean was 8:48 faster than Luke. Sean took official place 1171st (time-based 1064th) and Luke took official place 1167th (time-based 1191st). Luke's head start was enough to flip the official order even though Sean was faster on foot. Biggest swing: Sean gained 4:58 from Cardiac to White Gate.
