Interpretation

Noah (Z-DR) started at 8:51 AM; Roger (N-DR) started at 8:41 AM. That gave Roger a 10 minutes head start on Noah. On foot, Noah ran 1:17:47 and Roger ran 1:27:24 — Noah was 9:37 faster than Roger. Noah took official place 803rd (time-based 575th) and Roger took official place 798th (time-based 848th). Roger's head start was enough to flip the official order even though Noah was faster on foot. Biggest swing: Noah gained 4:58 from Cardiac to White Gate.
