Interpretation
Rob (Y-INV) started at 8:23 AM; Liem (X-INV) started at 8:22 AM. That gave Liem a 1 minute head start on Rob. On foot, Rob ran 1:01:50 and Liem ran 1:02:50 — Rob was 1:00 faster than Liem. Rob took official place 147th (time-based 104th) and Liem took official place 145th (time-based 131st). Liem's head start was enough to flip the official order even though Rob was faster on foot. Biggest swing: Rob gained 0:24 from Muir Woods to Cardiac.
