The thing I got from the text was the build up of deposits on the disc causes more trouble than actuall warping. Would need a properly researched article to get a more accurate view (these guys are selling brake upgrades afterall)..
I know for my 1100S forum brake judder and excessive wear becomes a common problem when performance pads are used with standard discs for road use - I'm still on the original discs at 39k - which for a bike seems pretty good, but then I think I get more problems from grubby calipers and pad glazing as the bike gets used mainly round the city and in all weathers.
I perhaps naively believe that a quality manufacturer would provide their product in an albeit compromised form balancing wear and performance
