With magazine tests, a lot of times, they correct for a standard degree day, 69 F, 29.92 barometric pressure, sea level, & most times they do not say that the ET & MPH were corrected for a standard degree day.
The typical correction factor for the track I used to race @ was typically 1/2 second.
So when I ran 14.3 seconds in my N/A 250 Camaro, with the correction factored in, it was really a 13.7 second pass!! WHEW!
But, I always post uncorrected times & MPH.
