Interpretation
Tracy (L-DR) started at 8:39 AM; Avery (H-DR) started at 8:36 AM. That gave Avery a 3 minutes head start on Tracy. On foot, Tracy ran 2:05:03 and Avery ran 2:06:18 — Tracy was 1:15 faster than Avery. Tracy took official place 1315th (time-based 1310th) and Avery took official place 1310th (time-based 1315th). Avery's head start was enough to flip the official order even though Tracy was faster on foot. Biggest swing: Tracy gained 2:57 from Cardiac to White Gate.
