Ok, so I understand the difference between absolute/station pressure and adjust sea level pressure.
I understand if using the Shooter app and I pull station pressure from a Kestrel or my Phone (Samsung Galaxy S3, which is dead on tits in reporting the pressure) that I check the absolute box and leave altitude blank.
I understand if I use the adjusted sea level pressure from my Suunto I need to also enter the elevation so it can calculate the station pressure of my location.
What I can't for some reason grasp, is if using the sea level pressure reported by the Suunto, is the elevation that the Suunto reports the correct number to enter or is the app based off the true calibrated elevation like from a USGS map or truly calibrated pressure at a known elevation? I know in the end getting it close is all that is really needed but I'm trying to just understand. As far as I can reason with myself the correct way is to use the sea level pressure and altitude reported by the Suunto and all is well but double checking.
