Interpretation
Peter (L-INV) started at 8:12 AM; Lisa (P-INV) started at 8:15 AM. That gave Peter a 3 minutes head start on Lisa. On foot, Peter ran 1:23:40 and Lisa ran 1:21:14 — Lisa was 2:26 faster than Peter. Peter took official place 459th (time-based 758th) and Lisa took official place 463rd (time-based 685th). Peter's head start was enough to flip the official order even though Lisa was faster on foot. Biggest swing: Lisa gained 1:30 from Muir Woods to Cardiac.
