Not sure some would agree...a few local Porsche club folks (drivers and 
shops servicing customer cars) report increased incidence of warped rotors 
when pads are worn to < 40% or so---even though there is lots of pad 
material left, there is less material to soak up heat--this is especially 
true if you use one of the popular carbon-kevlar products with a ceramic 
heat shield between the pad material and the backing plate.   For street 
use, not problem.
