Interpretation
Cameron (N-INV) started at 8:14 AM; Walter (Y-INV) started at 8:23 AM. That gave Cameron a 9 minutes head start on Walter. On foot, Cameron ran 1:27:15 and Walter ran 1:18:44 — Walter was 8:31 faster than Cameron. Cameron took official place 505th (time-based 839th) and Walter took official place 506th (time-based 604th). Cameron's head start was enough to flip the official order even though Walter was faster on foot. Biggest swing: Walter gained 3:30 from Muir Woods to Cardiac.
