Interpretation
Ren (Y-INV) started at 8:23 AM; Charles (U-INV) started at 8:19 AM. That gave Charles a 4 minutes head start on Ren. On foot, Ren ran 58:08 and Charles ran 1:02:04 — Ren was 3:56 faster than Charles. Ren took official place 67th (time-based 41st) and Charles took official place 64th (time-based 114th). Charles's head start was enough to flip the official order even though Ren was faster on foot. Biggest swing: Ren gained 1:16 from Cardiac to White Gate.
