The reference below is a minimum-time line solved from this track's geometry with a quasi-steady-state motorcycle model. It is a ceiling under ideal assumptions — use it to see where your headroom lives, then drop your own session file to measure yours.
Three places to look first
Biggest braking event
Turn 9: 150.5 → 40.6 km/h over 0.0 m. Brake-point consistency here is worth more than anywhere else on the lap.
Commitment corner
Turn 7: reference minimum 107.7 km/h. Fast corners punish hesitation — min-speed spread here is the classic amateur time leak.
Slowest corner
Turn 8: 39.2 km/h minimum. Exit drive from here sets the following straight — spread on the exit costs the whole next sector.
