Interpretation
Kevin (U-INV) started at 8:19 AM; David (P-INV) started at 8:15 AM. That gave David a 4 minutes head start on Kevin. On foot, Kevin ran 1:04:27 and David ran 1:08:22 — Kevin was 3:55 faster than David. Kevin took official place 113th (time-based 165th) and David took official place 110th (time-based 269th). David's head start was enough to flip the official order even though Kevin was faster on foot. Biggest swing: Kevin gained 1:40 from Cardiac to White Gate.
