Interpretation
Jonnie (L-DR) started at 8:39 AM; Edward (J-DR) started at 8:37 AM. That gave Edward a 2 minutes head start on Jonnie. On foot, Jonnie ran 1:46:00 and Edward ran 1:47:21 — Jonnie was 1:21 faster than Edward. Jonnie took official place 1158th (time-based 1179th) and Edward took official place 1153rd (time-based 1201st).
