Interpretation
Jon (Y-INV) started at 8:23 AM; Matthew (V-INV) started at 8:20 AM. That gave Matthew a 3 minutes head start on Jon. On foot, Jon ran 1:01:41 and Matthew ran 1:04:35 — Jon was 2:54 faster than Matthew. Jon took official place 143rd (time-based 101st) and Matthew took official place 138th (time-based 168th). Matthew's head start was enough to flip the official order even though Jon was faster on foot. Biggest swing: Jon gained 1:32 from Windy Gap to Muir Woods.
