Three places to look first
Biggest braking event
Turn 2: 167.9 → 105.3 km/h over 54.0 m. Brake-point consistency here is worth more than anywhere else on the lap.
Commitment corner
Turn 9: reference minimum 143.6 km/h. Fast corners punish hesitation — min-speed spread here is the classic amateur time leak.
Slowest corner
Turn 6: 75.2 km/h minimum. Exit drive from here sets the following straight — spread on the exit costs the whole next sector.
