Interpretation
Robb (Q-DR) started at 8:43 AM; John (V-DR) started at 8:47 AM. That gave Robb a 4 minutes head start on John. On foot, Robb ran 1:57:08 and John ran 1:53:48 — John was 3:20 faster than Robb. Robb took official place 1290th (time-based 1274th) and John took official place 1295th (time-based 1255th). Robb's head start was enough to flip the official order even though John was faster on foot. Biggest swing: John gained 2:38 from Muir Woods to Cardiac.
