Interpretation
Cooper (Z-INV) started at 8:24 AM; William (W-INV) started at 8:21 AM. That gave William a 3 minutes head start on Cooper. On foot, Cooper ran 1:12:51 and William ran 1:15:32 — Cooper was 2:41 faster than William. Cooper took official place 470th (time-based 416th) and William took official place 467th (time-based 504th). William's head start was enough to flip the official order even though Cooper was faster on foot. Biggest swing: Cooper gained 1:24 from Cardiac to White Gate.
