Interpretation
John (Y-DR) started at 8:50 AM; Eric (W-DR) started at 8:48 AM. That gave Eric a 2 minutes head start on John. On foot, John ran 1:04:45 and Eric ran 1:05:45 — John was 1:00 faster than Eric. John took official place 576th (time-based 175th) and Eric took official place 573rd (time-based 204th). Eric's head start was enough to flip the official order even though John was faster on foot. Biggest swing: John gained 1:02 from Windy Gap to Muir Woods.
