Interpretation
Robert (U-DR) started at 8:46 AM; David (P-DR) started at 8:42 AM. That gave David a 4 minutes head start on Robert. On foot, Robert ran 1:18:56 and David ran 1:22:46 — Robert was 3:50 faster than David. Robert took official place 721st (time-based 612th) and David took official place 716th (time-based 733rd). David's head start was enough to flip the official order even though Robert was faster on foot. Biggest swing: Robert gained 3:25 from Muir Woods to Cardiac.
