Level depends on grip conditions
The choice of level setting depends greatly on the
grip conditions of the track/circuit.
Level depends on type of track
If the track/path requires consistent braking (always
aggressive or always smooth), it will be easier to find
a level suitable for all braking instances; while a
track/path requiring different braking power will
require an EBC system level setting that is the best
compromise for all instances.
