Interpretation
John (Y-INV) started at 8:23 AM; Katherine (Q-INV) started at 8:16 AM. That gave Katherine a 7 minutes head start on John. On foot, John ran 1:02:22 and Katherine ran 1:09:20 — John was 6:58 faster than Katherine. John took official place 166th (time-based 120th) and Katherine took official place 165th (time-based 302nd). Katherine's head start was enough to flip the official order even though John was faster on foot. Biggest swing: John gained 2:17 from Cardiac to White Gate.
