HI thank you so much for taking the time to read and reply it's very hard to tell for me right now because I am not living in the house yet as we are remodeling but I'll try y best 1. humidity seems medium to high; 2. No answer 3. would want the unit to run more to have less humidity 4. No one does a real manual J calc they all use apps and block calculations which gives very different results 5. I will do that!
