Default Re: How much is good air worth?

I'm wondering if D/A is simply not D/A and comparing isn't as accurate as I once thought.

Tested at MIR on Oct 20th.

1.136 60'
3.227 330'
5.011 660'
137.22 mph

58.6 deg
57% humidity
29.82 barometer
354' D/A
42.50 grains

Now at a race at Cecil on Nov 2nd

1.136 60'
3.221 330'
5.002 660'
137.25 mph

57.4 deg
55% humidity
29.29 barometer
851' D/A
39.14 grains

The very next run at Cecil the car set the class record for an N/A car of 4.988.

I sit here comparing weather and at Cecil the barometer was way lower and higher D/A but the car still ran quicker. Scratching my head over this as when I looked at the weather station every run I expected the car to run slower than it had at MIR based on the air.

And I never did get to run in what I feel is mineshaft air this fall. Probably a good thing as I got hit with 50 lbs for running what it did. lol
