Interpretation
Henry (T-INV) started at 8:18 AM; Alena (Q-INV) started at 8:16 AM. That gave Alena a 2 minutes head start on Henry. On foot, Henry ran 1:16:22 and Alena ran 1:18:11 — Henry was 1:49 faster than Alena. Henry took official place 425th (time-based 535th) and Alena took official place 421st (time-based 584th). Alena's head start was enough to flip the official order even though Henry was faster on foot. Biggest swing: Henry gained 1:21 from Cardiac to White Gate.
