I see so high RH = higher vapor but we don't have an accurate test for vapor so our best guess is RH as a predictor. Let's leave Osmosis out of the conversation for now. How do I measure vapor if the science behind the ASTM is no good?

I can see this question happening to me and want to have my answer ready for some day...
