Interpretation
Noah (X-INV) started at 8:22 AM; Richard (T-INV) started at 8:18 AM. That gave Richard a 4 minutes head start on Noah. On foot, Noah ran 1:07:32 and Richard ran 1:11:27 — Noah was 3:55 faster than Richard. Noah took official place 275th (time-based 248th) and Richard took official place 270th (time-based 369th). Richard's head start was enough to flip the official order even though Noah was faster on foot. Biggest swing: Noah gained 1:16 from Cardiac to White Gate.
