Some times with 3.73 gears

So I've had my gears for a week now and I really like them. I had a chance to go to the track tonight, here are some times

I did like 20 runs, it wasn't a busy night( I love it ), here are some of my best.

Run 1
Reaction---.029
60ft-------2.070
1/8 ET-----8.855
1/4 ET-----13.693
1/4 MPH---105.287

Run 2
Reaction---.047
60ft-------2.069
1/8 ET-----8.827
1/4 ET-----13.653
1/4 MPH---105.637

Run 3
Reaction---.118 (I know )
60ft-------2.028
1/8 ET-----8.806
1/4 ET-----13.638
1/4 MPH---105.641

This is not my best time ever, but best of this year.

It looks good and all, but the weather was soo hot today (100F)

Here are the conditions

Temperature : 90 (with humidex felt like almost 100F)
Humidity : 69%
Track Altitude : 100ft
Pressure : 29.88
Density Altitude : 2560 feet

Here the weird thing

Density Altitude = 2560 feet ET MPH
Uncorrected 13.638 @ 105.641
Corrected 13.24 @ 108.76

It this possible?
