Interpretation
John (W-INV) started at 8:21 AM; Hector (Y-INV) started at 8:23 AM. That gave John a 2 minutes head start on Hector. On foot, John ran 1:23:17 and Hector ran 1:21:45 — Hector was 1:32 faster than John. John took official place 517th (time-based 749th) and Hector took official place 522nd (time-based 700th).
