Interpretation
John (U-INV) started at 8:19 AM; Emma (N-INV) started at 8:14 AM. That gave Emma a 5 minutes head start on John. On foot, John ran 1:01:02 and Emma ran 1:05:42 — John was 4:40 faster than Emma. John took official place 54th (time-based 81st) and Emma took official place 49th (time-based 201st). Emma's head start was enough to flip the official order even though John was faster on foot.
