Interpretation
Emily (Q-INV) started at 8:16 AM; Karl (P-INV) started at 8:15 AM. That gave Karl a 1 minute head start on Emily. On foot, Emily ran 1:15:45 and Karl ran 1:16:44 — Emily was 0:59 faster than Karl. Emily took official place 349th (time-based 515th) and Karl took official place 348th (time-based 542nd). Karl's head start was enough to flip the official order even though Emily was faster on foot.
