Interpretation
Tom (Y-INV) started at 8:23 AM; Andrew (V-INV) started at 8:20 AM. That gave Andrew a 3 minutes head start on Tom. On foot, Tom ran 1:08:44 and Andrew ran 1:11:34 — Tom was 2:50 faster than Andrew. Tom took official place 347th (time-based 281st) and Andrew took official place 343rd (time-based 374th). Andrew's head start was enough to flip the official order even though Tom was faster on foot. Biggest swing: Tom gained 1:03 from Muir Woods to Cardiac.
