Interpretation
Jakob (V-DR) started at 8:47 AM; John (X-DR) started at 8:49 AM. That gave Jakob a 2 minutes head start on John. On foot, Jakob ran 1:29:49 and John ran 1:27:57 — John was 1:52 faster than Jakob. Jakob took official place 1014th (time-based 907th) and John took official place 1019th (time-based 863rd). Jakob's head start was enough to flip the official order even though John was faster on foot. Biggest swing: John gained 2:32 from Muir Woods to Cardiac.
