Interpretation
Elliott (Z-DR) started at 8:51 AM; Mary (L-DR) started at 8:39 AM. That gave Mary a 12 minutes head start on Elliott. On foot, Elliott ran 1:20:39 and Mary ran 1:32:11 — Elliott was 11:32 faster than Mary. Elliott took official place 875th (time-based 666th) and Mary took official place 871st (time-based 948th). Mary's head start was enough to flip the official order even though Elliott was faster on foot. Biggest swing: Elliott gained 5:01 from Cardiac to White Gate.
