Interpretation
Dan (Y-DR) started at 8:50 AM; James (X-DR) started at 8:49 AM. That gave James a 1 minute head start on Dan. On foot, Dan ran 1:11:34 and James ran 1:12:14 — Dan was 0:40 faster than James. Dan took official place 662nd (time-based 373rd) and James took official place 659th (time-based 397th). James's head start was enough to flip the official order even though Dan was faster on foot. Biggest swing: James gained 1:58 from Muir Woods to Cardiac.
