Interpretation
Zach (Z-DR) started at 8:51 AM; Robert (R-DR) started at 8:44 AM. That gave Robert a 7 minutes head start on Zach. On foot, Zach ran 1:20:50 and Robert ran 1:27:43 — Zach was 6:53 faster than Robert. Zach took official place 884th (time-based 672nd) and Robert took official place 879th (time-based 857th). Robert's head start was enough to flip the official order even though Zach was faster on foot. Biggest swing: Zach gained 2:00 from Muir Woods to Cardiac.
