God I am confused. The hygrometers both read 73% 68F on the big one and 74% 68F on the little one after 24 hours with the salt test. No problem here because I was expecting it to be close to 75%. However, the one hygrometer has a max/min and the maximum it says it reached is 76%. Does that mean that my hygrometer is shy 2 or plus 1?
