Just as important, the decay times should be as even as possible over the entire range of frequencies. As it happens, I'm about to finish a video showing the RT60 as measured in a room 16 by 11.5 by 8 feet. The attached graph shows the decay times in third-octave bands for the room empty, then with a bunch of bass traps and reflection absorbers, and then again with diffusors covering all the remaining surfaces. You can see the huge improvement in uniformity with the diffusors in place.

Really looking forward to the video Ethan.
