Interpretation
David (P-INV) started at 8:15 AM; Paul (W-INV) started at 8:21 AM. That gave David a 6 minutes head start on Paul. On foot, David ran 1:18:31 and Paul ran 1:12:39 — Paul was 5:52 faster than David. David took official place 404th (time-based 594th) and Paul took official place 405th (time-based 411th). David's head start was enough to flip the official order even though Paul was faster on foot. Biggest swing: Paul gained 1:39 from Cardiac to White Gate.
