Interpretation
Kieran (Z-INV) started at 8:24 AM; Federico (X-INV) started at 8:22 AM. That gave Federico a 2 minutes head start on Kieran. On foot, Kieran ran 1:06:31 and Federico ran 1:08:30 — Kieran was 1:59 faster than Federico. Kieran took official place 301st (time-based 219th) and Federico took official place 300th (time-based 272nd). Federico's head start was enough to flip the official order even though Kieran was faster on foot. Biggest swing: Kieran gained 0:58 from Muir Woods to Cardiac.
