General practice tips
Tip 1
Starting point
Start with the official setup and consult the simulator documentation for available controls. Appropriate brake bias depends on the car and conditions.
Tip 2
One variable
Change one setting at a time and compare several laps. Record the change and observed behavior before keeping it.
Tip 3
Comparable conditions
Compare similar fuel loads, tires and track conditions. One lap alone does not establish that a setting is better.
