Thats not what i meant. Drive around aggressively and then take temps at different spots on the rotor, it can vary by quite a bit just on different spots. Not only that but if you were taking temps from various cars with similar brack setups then there are way too many variables in there to make it a reliable measurement. i.e. there is no experimental control.
About the only thing the IR gun will tell you is if one rotor is way hotter than another rotor. Which is useful for telling when the caliper brackets lock up on crap mustang brakes.
