Interpretation
Irvin (V-INV) started at 8:20 AM; Scott (T-INV) started at 8:18 AM. That gave Scott a 2 minutes head start on Irvin. On foot, Irvin ran 1:18:38 and Scott ran 1:20:16 — Irvin was 1:38 faster than Scott. Irvin took official place 492nd (time-based 598th) and Scott took official place 488th (time-based 655th).
