Very well explained and true . In my opinion when you start to know you car behaviour as it is you will know how to handle it accordingly . However generally speaking no matter how stock or modified is your vehicle ( suspension , tune , tires … etc ) I believe while you are performing specific manoeuvre from A to B like long sidy for example bear in mind that you don’t have much time ( split seconds ) to play with while doing it ( gas , gear shifter , let go gas … ) and that’s why achieving the momentum ( trick : bit higher not much ) from the start and keeping it constant before the entry point will let you have time to navigate within the momentum buffer without loosing it .
also flooring the gas paddle is seldom effective if you were not prepared ahead as the vehicle fluids response while in 45 degree inclination at long side or climb is totally different .
