Where the lap is won

Three places to look first

Biggest braking event

Turn 12: 125.9 → 35.3 km/h over 87.0 m. Brake-point consistency here is worth more than anywhere else on the lap.

Commitment corner

Turn 3: reference minimum 146.6 km/h. Fast corners punish hesitation — min-speed spread here is the classic amateur time leak.

Slowest corner

Turn 12: 35.3 km/h minimum. Exit drive from here sets the following straight — spread on the exit costs the whole next sector.
