No room correction algorithym is going to tame a bad room but it can help automate the process a lot. Even the best systems cannot account for subtle changes in the room and only yield one optimal position. If you want to tame your room, by all means use a room correction system but more as a starting point than the final arbiter of what is "right". Half the fun of having a complicated system is the tweaks we make to have it sound as good as it can. Although we refer to these systems as "room correction" they are really just fancy "room measurers" with some built in algorithyms of how someone thinks you will like the sound. In all actuality the only way to "correct the room" is to correct the room.
