Thanks for the clarification Alan, the inverses challenge my dyslexia too. I should have said "should" not "will." So 70/40 is the same as 80/30 and aprox 68/42? The link Alan sent is great, everyone should check it out if you find explaining this issue challenging. And what is absolute humidity? Anyone?
