Because every single autox and road racing veteran I've ever talked with has told me that... hee hee.
I believe the idea is that having r-compounds will allow you to not be as careful or refined when taking a line.
Let's say you take a line wrong (i.e. too fast and too jerky). In a street tire, that may cause you to slide a little and possibly spin out. In an r-compound, that "mistake" is absorbed by the extra stickiness of the tire; however, since it wasn't an optimal line, you are still losing tenths of a second - this all adds up and you won't be able to as easily figure out where you messed up. In effect, r-compounds "cover up" your mistakes, but you are still going slower than you could w/ r-compounds... it's all relative.
By having street tires, you can easily find out where you messed up on a course. Having R-compounds, it is much harder to determine where it is you screwed up.
Uneven wear on a tire is all relative depending on car setup & driving style - even tire wear doesn't mean better driver...
For me personally, I like driving basically the same exact setup at the course as I drive daily (for the most part). Really helps me get a better feel for my exact setup during sprited runs... or just driving around in general.
Hope that makes some sense.
