No but these two sites can help if you can't find someone with a weather station at the track

When I corrected my time on DragTimes I gained ~.2

If I understand correctly, this helps universalize 1/4 mile times.

That's why it was added.

Just post the real time and then if someone is curious, they can correct it to sea level. it isn't perfect, but it will give you an idea.

I wouldn't say they are as accurate as Kestrel weather station but they give you a close idea

Or is it 13.8?

you ran what your timeslip said you did. Lower DA just means you have better air. Dont get hung up on it.

Make no mistake, lower DA will give you better ET and MPH.

i understand that but it doesnt mean that if you run a 13.00 with a 2000 DA that you can use a calculator online and say you went 12.5 corrected. You still went 13.0.

Ya the calculators seem to be overly generous in most cases.
