Interpretation
Bill (M-INV) started at 8:13 AM; Andrew (Y-INV) started at 8:23 AM. That gave Bill a 10 minutes head start on Andrew. On foot, Bill ran 1:11:39 and Andrew ran 1:01:40 — Andrew was 9:59 faster than Bill. Bill took official place 140th (time-based 376th) and Andrew took official place 141st (time-based 99th).
