Interpretation
John (Z-DR) started at 8:51 AM; Tim (U-DR) started at 8:46 AM. That gave Tim a 5 minutes head start on John. On foot, John ran 1:13:27 and Tim ran 1:18:16 — John was 4:49 faster than Tim. John took official place 710th (time-based 435th) and Tim took official place 705th (time-based 587th). Tim's head start was enough to flip the official order even though John was faster on foot. Biggest swing: John gained 2:52 from Muir Woods to Cardiac.
