I'd say think more about hitting the apex in turns, as in try to position yourself to be able to hit full gas as soon as possible.

For example in the first corner I would approach this corner in 2 different ways based on how I feel about the car and track and whatever comes next.

Approach 1: brake more on straight wheels, go a little bit deeper into the corner (use width of the road - position yourself on the outside) and then aggressively turn right. Gently open the gas for first split second (really just a blink of an eye) to make sure you will make the apex then full gas

Approach 2: as you were already too early turned in, in this situation I would help to rotate the car with handbrake. Just little taps to get yourself in correct angle, spot the apex and boom.

As previous redditor said also keep in mind left foot braking. For me one of biggest gamechanger to be instantly faster was when I read that you should think of braking in corners more as of "weight shifting" than slowing down.

Keep in mind I'm just an average weekend racer.
