Interpretation
William (P-INV) started at 8:15 AM; Elton (V-INV) started at 8:20 AM. That gave William a 5 minutes head start on Elton. On foot, William ran 1:19:37 and Elton ran 1:14:45 — Elton was 4:52 faster than William. William took official place 431st (time-based 639th) and Elton took official place 434th (time-based 469th).
