Where the lap is won

Three places to look first

Biggest braking event

Turn 4: 103.0 → 62.9 km/h over 18.0 m. Brake-point consistency here is worth more than anywhere else on the lap.

Commitment corner

Turn 14: reference minimum 134.8 km/h. Fast corners punish hesitation — min-speed spread here is the classic amateur time leak.

Slowest corner

Skid Pad (T1): 35.1 km/h minimum. Exit drive from here sets the following straight — spread on the exit costs the whole next sector.
