Interpretation
Samantha (N-DR) started at 8:41 AM; David (Y-DR) started at 8:50 AM. That gave Samantha a 9 minutes head start on David. On foot, Samantha ran 1:29:33 and David ran 1:20:34 — David was 8:59 faster than Samantha. Samantha took official place 848th (time-based 896th) and David took official place 849th (time-based 665th). Samantha's head start was enough to flip the official order even though David was faster on foot. Biggest swing: David gained 3:01 from Muir Woods to Cardiac.
