I run a track car (Audi TT) and I bed in pads as follows:
10 stops from 80 to 20/30 firm pedal (about 70% pressure) and in a straight line.
Not had a problem with warping or anything yet, I think the 200 miles thing is a misnomer.
Believe me when I saw that I really don't want brake failure at some of the speeds I do on track!
I bed in my road cars the same way
