Most people I know use correction factor or DA. My car doesn't change much based on vapor pressure, nor water grains. I have a friend that gets hung up on the barometer. I can dial mine off the trailer within 01 (1/8th mile) just looking at the correction factor (except in Topeka LOL).
However, I have thought the same questions that you are asking...
