Interpretation
Greg (Y-INV) started at 8:23 AM; Ian (V-INV) started at 8:20 AM. That gave Ian a 3 minutes head start on Greg. On foot, Greg ran 1:12:35 and Ian ran 1:15:31 — Greg was 2:56 faster than Ian. Greg took official place 455th (time-based 410th) and Ian took official place 452nd (time-based 502nd). Ian's head start was enough to flip the official order even though Greg was faster on foot. Biggest swing: Greg gained 0:50 from Cardiac to White Gate.
