How drastically does DA effect e.t's

Went to the drag strip which will probably be the last time for us here in Ohio until Spring. I have a question regarding DA. Last time I was at the track the DA was 465 I ran my personal best 13.17. Today the DA was 1600 and I ran a 13.190 at 105 mph with a 1.945 6- footer. How much does DA play with your e.t's ? There was a drastic difference in DA from my last time yet my e.t's weren't too far apart from the day with the 465 DA. Just curious? I pulled out all the stops by putting the Goat on a diet and hyper-inflating the front tires for less rolling resistance. I'm pleased with my times because they are consistent yet I am curious what the DA cost me on a day like today?

Plug your times in a DA Calculator and find out. I'd guess about 2 tenths. If you had your trap for the first one I'd tell you. Go to the bottom of the page and plug your numbers in and I'd say use the "Mildly Modified" number. The DA calculator should be used by everyone as it gives a more accurate comparison not only for you to see improvement over another day but also to compare to someone living on the ocean to someone living in the mountains.
