Interpretation
William (P-INV) started at 8:15 AM; Christopher (U-INV) started at 8:19 AM. That gave William a 4 minutes head start on Christopher. On foot, William ran 1:19:37 and Christopher ran 1:15:42 — Christopher was 3:55 faster than William. William took official place 431st (time-based 639th) and Christopher took official place 433rd (time-based 511th).
