Interpretation
Samuel (V-INV) started at 8:20 AM; Alex (Y-INV) started at 8:23 AM. That gave Samuel a 3 minutes head start on Alex. On foot, Samuel ran 57:18 and Alex ran 54:53 — Alex was 2:25 faster than Samuel. Samuel took official place 31st (time-based 34th) and Alex took official place 35th (time-based 18th). Samuel's head start was enough to flip the official order even though Alex was faster on foot. Biggest swing: Alex gained 1:35 from Muir Woods to Cardiac.
