Yes I do. Once the setup is right I don't spend much time with zone temps but I am more interested in comparing hot temps to lap data. Different tires have a different sweet spot in terms of heat and I like to keep them in the zone for Time Trials and AX.
To answer the OP I typically air to around 29psi in the first session AM and then air down as needed to get 32-34psi hot. At this pressure and on current tires around 110F I am getting my best grip data and lap times. I keep a log of this and as tire choices change, I log them as well.
