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

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

Gets back to what I said, I think you are going DOWNHILL at Cecil, just like 4 wide/concord, simply put, the startingline elevation is higher that the finishline elevation
