To get even temps across the tire when you don't have proper camber, you won't be using the outside tread enough, and therefore, not using the whole tire. It's a good tool, but I wouldn't set my pressures because of it. That being said, it's easy to bleed down your pressures, and I don't think the tires are all that sensitive to pressure since they are fairly stiff.

+1 to this. At one point in CS trim I tried to tune tire pressure with a pyrometer. Even accepting that one third of the tire won't match the other two, I ended up pretty unhappy with the car, and ditched those pressures in favor of the ones that felt fast and were fast on the clock.
IMO there is a lot of setup procedures that are the "right" thing to do, but you end up ditching in Street class because you're too hobbled to actually setup the car right. (Obligatory "this is why I left"...)
