Great follow up dcaron. Thanks for posting that. I have found pressures to be a minor, but impactful adjustment. My last time at Sonoma in November, even the RFTs were really good (as good as they can be) in one of the warmer sessions around mid-day, but then the next session the shadows started to come out and it was like driving on ice.

My general rule of thumb is to start a couple PSI below the door jam numbers when it's cold in the morning, then continue to drop a little more as it warms up, and start adding it back in if it starts getting cool again late in the day. I have a temperature probe to help add some data to make the right adjustment, but you have to be diligent about coming directly to the pits as fast as possible to get reasonably reliable readings.
