My brake point at Turn 1 moved forty-two meters lap to lap. That’s nine-tenths of a second of pure guessing, and it explains almost everything else the data told me about Saturday at Eagles Canyon. Three HPDE sessions at Eagles Canyon Raceway in a 718 Boxster GTS 4.0, 16 timed laps of RaceChrono data, and a 4.53-second gap that traces back to inconsistent brake points.
