This makes it possible to achieve the legally required minimum deceleration of 0.3 g with a pedal force of 500 N.

Possible- not probable. It also means it may NOT be possible unless you apply the full 500n of force; you may get NO braking at all. More than a few owners online have stated there was no warning whatsoever when their SBC brakes failed. Why on earth would you try to deny that? What do you have to gain?
