Interpretation
Ryan (Y-DR) started at 8:50 AM; David (G-DR) started at 8:35 AM. That gave David a 15 minutes head start on Ryan. On foot, Ryan ran 1:43:53 and David ran 1:58:23 — Ryan was 14:30 faster than David. Ryan took official place 1256th (time-based 1154th) and David took official place 1252nd (time-based 1281st). David's head start was enough to flip the official order even though Ryan was faster on foot. Biggest swing: Ryan gained 5:29 from Muir Woods to Cardiac.
