Interpretation
Ivy (N-DR) started at 8:41 AM; Sally (Q-DR) started at 8:43 AM. That gave Ivy a 2 minutes head start on Sally. On foot, Ivy ran 1:59:15 and Sally ran 1:57:58 — Sally was 1:17 faster than Ivy. Ivy took official place 1291st (time-based 1284th) and Sally took official place 1296th (time-based 1278th). Ivy's head start was enough to flip the official order even though Sally was faster on foot. Biggest swing: Sally gained 1:57 from Cardiac to White Gate.
