Establish the entry
Pick a visible reference point such as a road marking, barrier or building edge. It does not have to be perfect; it has to be repeatable. If entry speed and position change every run, the rest of the corner becomes difficult to evaluate.
Let the car rotate
If the car does not rotate as expected, adding more steering is not always the answer. You may have entered too quickly, applied steering too abruptly, or asked the tires to do too much at once. Try a smaller change and observe what happens.
Protect the exit
The exit is connected to what comes next. Running wide may sacrifice the following section even if the current corner looked fast. A controlled exit gives you room to accelerate and prepare for the next input.
Describe repeated mistakes precisely
“The car feels bad” is hard to act on. “The front runs wide after throttle is added on exit” gives you a specific behavior to investigate. Precise descriptions make both practice and tuning more productive.
