I just got done running two packs through the GLR and the car is off pace right now. Last night I ran a couple packs and got within .07s of Scionara's but was not as clean as I needed to be but the car was fast regularly doing 4.0X's and dipping into the 3's fairly often. Just now I felt fast and was super consistent, I did 6 consecutive laps at 4.17s, but I just could not get the car to turn fast laps. I changed nothing on the car so what happened? I am guessing it is atmospherics conditions, it is way more humid today then it was yesterday and I am thinking that is the cause of my slower than normal times. It is pretty amazing that the humidity level can cause such a large change in lap times.
This may be the end of my bid to get fastest stint time for the month as the track has to come down this evening and I do not think it will be back up again this month.

your not wrong on air temp change. In my basement with the ac off I noticed I would be doing 4.10 to 4.06 but then the ac kicks on and the temp changes then I start seeing the 3.89 to 3.99 coconsecutive laps. So what I tend to do is wait till the ac starts do a 75 then wait for it to cycle. My ac keeps my house at 75 so the temps a big difference in the basement sitting right next to it
