Interpretation
Jason (W-INV) started at 8:21 AM; Brian (E-INV) started at 8:06 AM. That gave Brian a 15 minutes head start on Jason. On foot, Jason ran 1:12:56 and Brian ran 1:27:51 — Jason was 14:55 faster than Brian. Jason took official place 413th (time-based 424th) and Brian took official place 411th (time-based 860th). Brian's head start was enough to flip the official order even though Jason was faster on foot. Biggest swing: Jason gained 4:42 from Muir Woods to Cardiac.
