Interpretation
Jackson (SCR-DR) started at 8:52 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 42 minutes head start on Jackson because the Runner wave starts 27 minutes after the Invitational wave. On foot, Jackson ran 58:43 and Chris ran 1:00:42 — Jackson was 1:59 faster than Chris. Jackson took official place 549th (time-based 48th) and Chris took official place 1st (time-based 71st). Chris's head start was enough to flip the official order even though Jackson was faster on foot. Biggest swing: Jackson gained 0:37 from Cardiac to White Gate.
