Where lap 23 beat lap 27
The session report's speed graph runs on elapsed time, which cannot say where time changed hands — two laps at the same second are not at the same place. Play starts both laps together and follows each lap’s own clock. The chart and distance slider compare equal distances. As it happens, at 34 s the two were only 6 m apart on track, so that reading held up.
Lap 23 — fastest — 43.848s
Lap 27 — median comparison — 44.497s
Lap 27 is the upper-middle recorded flying lap (rank 25 of 48 by lap time), used for the median comparison. Its actual time is 44.497s; the statistical median of the two middle times is 44.4625s.
