Interpretation
Isobel (H-DR) started at 8:36 AM; Bobby (V-DR) started at 8:47 AM. That gave Isobel a 11 minutes head start on Bobby. On foot, Isobel ran 1:35:54 and Bobby ran 1:25:11 — Bobby was 10:43 faster than Isobel. Isobel took official place 885th (time-based 1030th) and Bobby took official place 890th (time-based 793rd). Isobel's head start was enough to flip the official order even though Bobby was faster on foot. Biggest swing: Bobby gained 4:04 from Muir Woods to Cardiac.
