Interpretation
John (Y-INV) started at 8:23 AM; Sam (W-INV) started at 8:21 AM. That gave Sam a 2 minutes head start on John. On foot, John ran 1:02:22 and Sam ran 1:04:17 — John was 1:55 faster than Sam. John took official place 166th (time-based 120th) and Sam took official place 162nd (time-based 160th). Sam's head start was enough to flip the official order even though John was faster on foot.
