Interpretation
Matthew (X-INV) started at 8:22 AM; James (AAA-INV) started at 8:00 AM. That gave James a 22 minutes head start on Matthew. On foot, Matthew ran 1:19:46 and James ran 1:40:26 — Matthew was 20:40 faster than James. Matthew took official place 507th (time-based 645th) and James took official place 504th (time-based 1100th).
