Interpretation
Robert (X-DR) started at 8:49 AM; Todd (P-DR) started at 8:42 AM. That gave Todd a 7 minutes head start on Robert. On foot, Robert ran 1:24:13 and Todd ran 1:30:58 — Robert was 6:45 faster than Todd. Robert took official place 913th (time-based 776th) and Todd took official place 909th (time-based 925th). Todd's head start was enough to flip the official order even though Robert was faster on foot. Biggest swing: Robert gained 3:20 from Muir Woods to Cardiac.
