Interpretation
Elsie (M-DR) started at 8:40 AM; Dave (AAA-INV) started at 8:00 AM. That gave Dave a 40 minutes head start on Elsie because the Runner wave starts 27 minutes after the Invitational wave. On foot, Elsie ran 1:16:47 and Dave ran 1:56:44 — Elsie was 39:57 faster than Dave. Elsie took official place 597th (time-based 543rd) and Dave took official place 596th (time-based 1270th). Dave's head start was enough to flip the official order even though Elsie was faster on foot. Biggest swing: Elsie gained 14:27 from Muir Woods to Cardiac.
