I set a 75db target but it does not appear un 'measured' window. Does it matter ?
By the way, here are the RT60 results for the Stereo+sub and stereo only measured. Looks quite good to me but is it realistic ?

Next one is the Waterfall for Stereo+sub. I'm not sure about the interpretation of this ...
