DE Tire Pressures

[CarreraS]

OK, every time I ask this question at the track I get a different answer.  So, now is the chance to get 30 different answers on the forum! 

Scenario: 997s...19 inch wheels with Pirelli stock tires...cold inflation recommended at 37/44

At the most recent T-bolt event a couple of weeks ago, I set the pressures at 32/37 cold.  After each session, I was consistently at 37/41 hot.  Car felt great except through the octopus and that was definitely more my fault than the tire settings.  I did notice some sidewall wear on the driver's side front.

Am I in the right ballpark with where I'm setting my pressures when cold?

Also, I'm doing the SCH T-bolt event on Saturday with expected temperatures to be significantly lower than a couple of weeks ago.  Do I go with a cold setting closer to the recommended settings?

All you fast guys, please throw in your two cents.  Thanks!!
