If you go to the track frequently then excessive wear from street driving is a non issue. Unless you're running on rock wheels fred flinstone style, you'll wear out the tires from track use. If you run a lot of camber on the street, the insides wear. But on the track, most of your wear comes on the outside shoulder. A square setup will extend tire life significantly. I try to stick to this rotation with directional tires:

Swap front to rear
Flip all 4 tires/same corner
Swap front to rear

...then I haven't gotten past that.

If you run assymetrical tires (like PSS)...I'd just rotate the best tire to the corner which will see the most wear and then the worst tire to the corner that will see the least amount of wear. But I'm not an expert on that.

This is what my E46 tires looked like after 50 sessions + 2 wet days + 6k street miles. I didn't even flip them...probably could have gotten a couple more sessions.
