Interpretation
Tom (W-DR) started at 8:48 AM; Meryl (Q-DR) started at 8:43 AM. That gave Meryl a 5 minutes head start on Tom. On foot, Tom ran 1:24:47 and Meryl ran 1:29:37 — Tom was 4:50 faster than Meryl. Tom took official place 907th (time-based 786th) and Meryl took official place 903rd (time-based 901st). Meryl's head start was enough to flip the official order even though Tom was faster on foot. Biggest swing: Tom gained 2:28 from Muir Woods to Cardiac.
