Interpretation
Edward (Y-INV) started at 8:23 AM; John (K-INV) started at 8:11 AM. That gave John a 12 minutes head start on Edward. On foot, Edward ran 56:56 and John ran 1:08:53 — Edward was 11:57 faster than John. Edward took official place 52nd (time-based 31st) and John took official place 51st (time-based 287th).
