Interpretation
Robert (AA-DR) started at 8:28 AM; Jacob (X-INV) started at 8:22 AM. That gave Jacob a 6 minutes head start on Robert because the Runner wave starts 27 minutes after the Invitational wave. On foot, Robert ran 2:28:24 and Jacob ran 2:34:04 — Robert was 5:40 faster than Jacob. Robert took official place 1356th (time-based 1366th) and Jacob took official place 1355th (time-based 1371st). Jacob's head start was enough to flip the official order even though Robert was faster on foot. Biggest swing: Jacob gained 6:42 from Cardiac to White Gate.
