As Myron said, weather that changes a fast car .04 will change his car .1-.15, and you can never tell what the margin will be. His weather station thingy has proven to be almost useless.
The one advantage he has is the car will not spin even on the worst tracks.

Mmmm.... never say never. I went to an NHRA national event last year, and had the Turismo running great first two days. For first round of eliminations, the barometer had dropped like a stone. My E.T. predictor said .15 slow. Oh, BTW, we had a 22 mph direct tailwind! I dialed DOWN. First round of eliminations, blew the tire off. Spun .08 and missed the dial by... you guessed it, .08.

Mm.
But yah, it's typically a 3:1 or 4:1 change over an 11-sec car. No substitute for seat time. You may dial big changes, but it can still be somewhat predictable with experience.
