Interpretation
Michael (U-INV) started at 8:19 AM; Gary (P-INV) started at 8:15 AM. That gave Gary a 4 minutes head start on Michael. On foot, Michael ran 1:11:15 and Gary ran 1:15:15 — Michael was 4:00 faster than Gary. Michael took official place 293rd (time-based 356th) and Gary took official place 292nd (time-based 493rd). Gary's head start was enough to flip the official order even though Michael was faster on foot. Biggest swing: Michael gained 1:11 from Cardiac to White Gate.
