Interpretation
David (Y-INV) started at 8:23 AM; Stan (AA-INV) started at 8:01 AM. That gave Stan a 22 minutes head start on David. On foot, David ran 1:10:15 and Stan ran 1:32:05 — David was 21:50 faster than Stan. David took official place 397th (time-based 334th) and Stan took official place 393rd (time-based 945th). Stan's head start was enough to flip the official order even though David was faster on foot. Biggest swing: David gained 8:07 from Muir Woods to Cardiac.
