Interpretation
Walter (AAA-DR) started at 8:27 AM; Knute (P-DR) started at 8:42 AM. That gave Walter a 15 minutes head start on Knute. On foot, Walter ran 2:49:57 and Knute ran 2:40:04 — Knute was 9:53 faster than Walter. Walter took official place 1388th (time-based 1385th) and Knute took official place 1391st (time-based 1378th). Walter's head start was enough to flip the official order even though Knute was faster on foot. Biggest swing: Walter gained 8:02 from Muir Woods to Cardiac.
