Interpretation
Anna (P-INV) started at 8:15 AM; Shyla (N-INV) started at 8:14 AM. That gave Shyla a 1 minute head start on Anna. On foot, Anna ran 1:17:07 and Shyla ran 1:18:01 — Anna was 0:54 faster than Shyla. Anna took official place 358th (time-based 558th) and Shyla took official place 356th (time-based 582nd). Shyla's head start was enough to flip the official order even though Anna was faster on foot.
