Quick question on my DA correction. I'm new to trying to figure out the correct DA and adjusted times. I adjusted my run tonight and wanted to know if this looks right?
Uncorrected:
85*F
47% Humidity
(It figured the Pressure was 30.15in on it's own)
500ft. Track Elevation
13.166@106.96 (this was with a 60' of 2.048)
"Corrected:"
DA = 2261ft.
12.83@109.71

I followed the link on that site to www.accuweather.com to get the real readings from last night and not just going off memory.
Uncorrected:
82*F
71% Humidity
29.92in Pressure
500ft. Track Elevation
13.166@106.96 (this was with a 60' of 2.048)
"Corrected:"
DA = 2428ft.
12.8@109.94
I wasn't too far off.

looks close, I just did one of my runs from yesterday (already knowing actual DA, temp and so on), and it corrected my 11.639 at 114.41 to an 11.15 at 119. for sea level, which is a little too far off. The calculated DA they gave was 3485 and measured was 3467, so it was close, but my car hasn't even hit the 11.20's. Just remember, correction factors are great, but they don't replace an actual run in better air. And I've always found the 100 lbs/1000 ft DA = 1 tenth works pretty well.
Just my $.02
