What is the correct procedure for performing a hill start (arranque em rampa / subida acentuada) in a manual transmission car to prevent rolling backwards?

1. Engage 1st gear with handbrake on, press accelerator gently to 1,500 RPM, bring clutch pedal up to the bite point (ponto de embraiagem) until the rear dips slightly, hold both feet steady, and release the handbrake smoothly as the car moves forward
2. Release the handbrake first, then search for 1st gear while the car rolls backwards
3. Rev the engine to 5,000 RPM and drop the clutch pedal instantly
4. Shift into neutral and let the vehicle roll into the curb to stop it
