Interpretation
William (X-INV) started at 8:22 AM; David (P-INV) started at 8:15 AM. That gave David a 7 minutes head start on William. On foot, William ran 1:04:10 and David ran 1:10:54 — William was 6:44 faster than David. William took official place 180th (time-based 158th) and David took official place 178th (time-based 352nd).
