Interpretation
Mike (Y-DR) started at 8:50 AM; Brian (X-DR) started at 8:49 AM. That gave Brian a 1 minute head start on Mike. On foot, Mike ran 1:16:35 and Brian ran 1:17:31 — Mike was 0:56 faster than Brian. Mike took official place 755th (time-based 541st) and Brian took official place 753rd (time-based 569th). Brian's head start was enough to flip the official order even though Mike was faster on foot. Biggest swing: Mike gained 2:05 from Muir Woods to Cardiac.
