Understand where your coming from. Perhaps that's it? dunno though, and I recall a lot of non turbo'd drivers complaining too.
Maybe those people are going too slow in the corners compared to you so need to slow down more.
The one time we had really bad fade on ds2500 in a fairly standard car was the session after my mrs had a spin at bedford, and she was a bit spooked by it so was slowing down far too much for each corner afterwards, she came in with the brakes faded to hell, but when I took it out on the next session I had no problems as I was carrying more corner speed than her so wasnt braking as much.
Its about a combination of:
speed the car is going before braking (power/weight)
speed the car is going after braking (cornering ability)
how hard and late you actually brake to achieve that drop in speed and hence how long they have to cool actually during the application of the braking not just after it
with the ds2500 for example, the deposits MG cup is talking about, IME you simply dont get if you brake relatively early and not too hard even if slowing down quite a lot, but you do get them if you stand on the brakes at the last second really hard.
