I think that the transfer of pad material only occurs with higher temperatures. If you are using for daily driving (frequent cold brake rotors) then the pad material will eventually wear off of the rotor face. When I ran Cool Carbons as my DD and track pad (not so great), I would have to re-bed every month or so when they would start squealing again. I know that my Pagids will scrub my rotors clean within a couple of days after track events so I can put back the street pads and re-bed them back in.
