Interpretation
David (Y-INV) started at 8:23 AM; Stephen (V-INV) started at 8:20 AM. That gave Stephen a 3 minutes head start on David. On foot, David ran 59:00 and Stephen ran 1:02:00 — David was 3:00 faster than Stephen. David took official place 85th (time-based 54th) and Stephen took official place 84th (time-based 112th). Stephen's head start was enough to flip the official order even though David was faster on foot. Biggest swing: David gained 0:35 from White Gate to The Stile.
