How much does weather effect you ET and MPH?

With the cooler weather coming I have visions of low 12s coming.:)

My best in my sig was at 75* and 70% humidity. With temps in the low 50's high 40's how much of an improvment can I expect?

Im aware of the calculators....I want real life experiences and improvements.

I would probably expect around 2 tenths give or take. I am also looking to better my times as the weather cools, but after a certain point you just can't get that extra power down on a cold track.

In 85* and 85 humidity, I ran a 13.47. In 65* and 85 humidity, times are in the sig. Heck ya it makes a difference. Once it gets down to the 50's I'm expecting 12 second passes.
