Interpretation
Ken (N-INV) started at 8:14 AM; Dave (K-INV) started at 8:11 AM. That gave Dave a 3 minutes head start on Ken. On foot, Ken ran 1:13:34 and Dave ran 1:16:22 — Ken was 2:48 faster than Dave. Ken took official place 217th (time-based 437th) and Dave took official place 214th (time-based 536th). Dave's head start was enough to flip the official order even though Ken was faster on foot. Biggest swing: Ken gained 2:01 from Muir Woods to Cardiac.
