Interpretation
Jon (Y-INV) started at 8:23 AM; Bill (M-INV) started at 8:13 AM. That gave Bill a 10 minutes head start on Jon. On foot, Jon ran 1:01:41 and Bill ran 1:11:39 — Jon was 9:58 faster than Bill. Jon took official place 143rd (time-based 101st) and Bill took official place 140th (time-based 376th). Bill's head start was enough to flip the official order even though Jon was faster on foot. Biggest swing: Jon gained 3:02 from Cardiac to White Gate.
