I think it does effect overall braking power.
Last weekend i was up testing and i updated to V11.6 i took the car out for a run and realised i had seriouly bad brakes, the minute i went back i checked the settings and i had forgot to tick the "new brake" box. once i did this the brakes were back to itsnormal feel.
Its worth a try anyway but i thing it dramatically helps.
