Interpretation
Olivia (M-INV) started at 8:13 AM; Frank (P-INV) started at 8:15 AM. That gave Olivia a 2 minutes head start on Frank. On foot, Olivia ran 1:13:18 and Frank ran 1:11:21 — Frank was 1:57 faster than Olivia. Olivia took official place 184th (time-based 431st) and Frank took official place 186th (time-based 363rd).
