Interpretation
Robert (V-INV) started at 8:20 AM; Isaac (Y-INV) started at 8:23 AM. That gave Robert a 3 minutes head start on Isaac. On foot, Robert ran 1:11:48 and Isaac ran 1:09:00 — Isaac was 2:48 faster than Robert. Robert took official place 351st (time-based 384th) and Isaac took official place 355th (time-based 292nd).
