Interpretation
Michael (Y-INV) started at 8:23 AM; Stephen (V-INV) started at 8:20 AM. That gave Stephen a 3 minutes head start on Michael. On foot, Michael ran 59:04 and Stephen ran 1:02:00 — Michael was 2:56 faster than Stephen. Michael took official place 87th (time-based 55th) and Stephen took official place 84th (time-based 112th). Stephen's head start was enough to flip the official order even though Michael was faster on foot. Biggest swing: Michael gained 0:48 from Windy Gap to Muir Woods.
