correction factors et and speed high altitude tracks

Folks,

Many of you travel all around EU to race. Many tracks are on different altitudes. Below is a table with correction factors that will provide you the time the car would have ran when the track was at sea level (like Drachten). E.g. Bitburg is at 4800ft above sea level.

I hope it is usefull.

NHRA Elevation Correction Factor
> To convert your timeslip ET and MPH to sea level. Multiply
> applicable factor times your ET or MPH.

> The correction factors are .9367 and 1.0661 for 5000'. (13.8
> * .9367) = 12.93 , (100 * 1.0661) = 106.61 MPH. So the correct
> timeslip would be 12.93 @ 106.61 MPH.)
