Correction for DA?

Correction for DA?
I was just wondering if correcting your times for the DA was a legitimate way to find your times. I recently ran in Phx and the DA was ~2300ft. I ran the times in my sig. I used a DA calculator to correct it and it said my time corrected was 13.9x @ 99.xx.
So I guess it's more of a pride question. Do I consider my car a high 13 sec car or do I just deal with the 14 sec for now?
Just something I was thinking about.

Yeah, that's what I used to correct my times according to the DA. My question is this:
Do you go by your actual time from the time slip, or is it accepted to use DA corrected times?
Without the correction I have a 14 sec car. With the correction I have a 13 sec car.
When talking about what times I've run do I use the corrected time?
Sorry if this is confusing. It made sense in my head.

Thanks for clearing that up guys.
EDIT: So if I use one of those HP calculators, which time should I put in? It doesn't give an option for DA on the calculators.

You input all the numbers from the slip and it will calculate the DA for you along with the corrected numbers.
As we've all said tho - if you're going to post what you ran, post from the slip. Otherwise you're just another tool in my book.
Correction is great when used properly

Doing a correction for DA is only a theoretical ET to what the car could do at sea level. Even a sea level track is rarely at sea level DA especially during the summer. On occasion in the early spring or late fall, a sea level track can have a DA well below sea level. The car will normally perform very well in this good air.
I race at 3500' altitude with a DA usually hovering around 5000'. I went to a 2500' altitude track last year that had a DA around 3000' and the car ran the same ET. I never changed the tune for the lower elevation.
What you get on a timeslip is what the car runs. It will usually run better at lower elevation tracks but don't always expect it to.
A car that gets a 12 second timeslip in Denver is still faster than a car that gets a 12 second timeslip in Florida. It's just tuned differently.
