er, a bit hard to tell u here. u need to learn thru experience
and also know abit of the theory.
theoratically, the braking pt is the idea point to brake for
entry to a corner.
the racing line, theoratically, is the idea line thru a corner.
might not be the fastest line thru the corner, but the one most
suited taking into account the layout of the circuit of the track
before and after it.
