Default how can i figure in altitude???

The guy before me ran a 12.76 @ 105.8mph on a 1.76 60 ft at 1200 ft above sea level when it was around 60-65 degrees. Is there a formula I can try that will help me to find out what I would run in the same weather at about 30 feet above sea level?

Please don't ever post "corrected" timeslips though...thanks

I've seen people do this and it REALLY gets under my skin. Use it as a way of seeing how your car WOULD stack up against someone who is running at a better track than you are.

I actually went through it all and wrote up a "how to" article here https://ls1tech.com/forums/drag-racing-tech/618161-here-instructions-what-would-have-run-sea-level.html
