Interpretation
Summit (V-INV) started at 8:20 AM; Kelly (P-INV) started at 8:15 AM. That gave Kelly a 5 minutes head start on Summit. On foot, Summit ran 1:13:58 and Kelly ran 1:18:54 — Summit was 4:56 faster than Kelly. Summit took official place 415th (time-based 450th) and Kelly took official place 412th (time-based 609th). Kelly's head start was enough to flip the official order even though Summit was faster on foot. Biggest swing: Summit gained 1:49 from Muir Woods to Cardiac.
