Interpretation
William (V-DR) started at 8:47 AM; Kenji (P-DR) started at 8:42 AM. That gave Kenji a 5 minutes head start on William. On foot, William ran 1:28:51 and Kenji ran 1:33:41 — William was 4:50 faster than Kenji. William took official place 978th (time-based 881st) and Kenji took official place 974th (time-based 979th). Kenji's head start was enough to flip the official order even though William was faster on foot. Biggest swing: William gained 3:48 from Cardiac to White Gate.
