I don't buy the "breaking in" thing about hub mounted disc brakes nor that it should take 300 miles (roughly 25 hours) to do so. Nothing else on a bike has that kind of break in period. I do have hub mounted discs on some of my bikes and haven't needed more than a ride down the block and back to "break in" the brakes. Taking that long to get something to work properly isn't breaking the component in but it's a case of you adapting to it.
By the way, I feel the same way about Brooks saddles. Never had a "break in" period on them either. They worked just fine right out of the box and none of them, despite thousands of hours of use, is any softer than they were coming out of the box.
