How true is Density Altitude and drag racing?

The last time I looked at my buddies weather station at the track compared to what dragtimes said I think it was around 400-600 off from the actual "At the track DA"
Could vary though. I wouldn't rely on it 100%, thats for sure. I know in 2100(-+)DA I'll run a 6.98-7.02 all day and in 3000(-+)DA I'll run around a 7.15.
Like everyone else is saying these so many more variables than just DA.

I prefer this calculator
http://www.modulardepot.com/?show=density2
I have used the calculators from many places and by far this one seems to be the closest.... My track altitude is based at 2400' add the DA and it comes to 3k-5800 at times
We did have a 1700' DA night last march
but i could not run
