Interpretation
Bill (M-INV) started at 8:13 AM; David (J-INV) started at 8:10 AM. That gave David a 3 minutes head start on Bill. On foot, Bill ran 1:11:39 and David ran 1:14:33 — Bill was 2:54 faster than David. Bill took official place 140th (time-based 376th) and David took official place 137th (time-based 463rd). David's head start was enough to flip the official order even though Bill was faster on foot. Biggest swing: Bill gained 1:26 from Muir Woods to Cardiac.
