I ran across this doc today, which is interesting reading to help understand what Davis gear reports for derived values and why.
In my case I was seeing a 13 mbar offset in station pressure between my VP2 and several WeatherFlow stations that I'm a beta tester for. I suspected that the difference was the Davis correcting the reported pressure for altitude. A little more research finding a simple lookup table at https://novalynx.com/manuals/bp-elevation-correction-tables.pdf agreed with that guess.
