Interpretation
Peter (AAA-DR) started at 8:27 AM; Dave (K-DR) started at 8:38 AM. That gave Peter a 11 minutes head start on Dave. On foot, Peter ran 1:27:07 and Dave ran 1:16:57 — Dave was 10:10 faster than Peter. Peter took official place 574th (time-based 832nd) and Dave took official place 579th (time-based 551st). Peter's head start was enough to flip the official order even though Dave was faster on foot.
