Tuning a room by EQ is something that needs an experienced person to intrepret the data and make informed adjustments beyond what the raw numbers may say. Just sticking a microphone up at the listening position and pushing the "auto EQ" button doesn't cut it. It is way, way better to deal with room nodes by placement and acoustic treatment than by EQ if at all possible - EQ should be the last resort since it does not correct the problem at all, but just covers up the symptoms. The resonances are still there, storing and releasing energy, but are just decreased in amplitude.
