ET Prediction Software

We use a ~1994 Casio Calculator for Density Altitude that my Dad had bought as part of an DA kit when he raced S/C. We since replaced the temp and humidity gage with a $15 digital one from amazon that we checked against others ones around our 2 houses to be safe. We have an analog altimeter too. We track our runs in the attached excel document I came up with. I do a trend line sometimes and/or just best guess when I know the DA. All bracket racing around Michigan has gone 1/8th mile and the et's reflect that. It works ok, more consistent than the driver, that's for sure!

Wouldn't let me attached the excel file for whatever reason. So here are some screenshots.
