Q: How do I know if I’m over-slowing by left-foot-braking?

Q: “I am very comfortable using left-foot-braking and have found many situations where it seems to be an advantage, but other than lap times, how can I know if I’m really using left foot braking too often or too much? I switch between right and left foot, depending on the corner, and sometimes I feel that I over-slow the car when braking with my left foot.”

Q: How do I know if I’m causing under/oversteer, or it’s the car that’s doing it?

Q: “Specifically, on the entry phase, how does one determine whether it is steering (amount of steering or rate of input) or braking input (or more generally the rate of deceleration in a linear sense) that is the cause of over/understeer while turning in? More briefly, how does one know if they have applied too much linear deceleration or tried to induce too much rotation?”
