Interpretation
David (P-INV) started at 8:15 AM; Michael (V-INV) started at 8:20 AM. That gave David a 5 minutes head start on Michael. On foot, David ran 1:08:22 and Michael ran 1:03:23 — Michael was 4:59 faster than David. David took official place 110th (time-based 269th) and Michael took official place 111th (time-based 145th). David's head start was enough to flip the official order even though Michael was faster on foot. Biggest swing: Michael gained 1:30 from Muir Woods to Cardiac.
