I hate this conform-o-meter item with a passion. I refuse to try and hide a bunch of training walls. With all the vast amount of stuff we have there should be all sorts of stuff that grant points to this one. Also I've been told in the past that tasks don't change the rating. Only the training walls and removing graffiti. I rarely have graffiti to remove. And yet my rating bounces from 5 to 0.5 stars all the time but always with a large amount of stuck at one or the other end for a long time. No obvious cause, it seems to be random. It has been this way since I started playing about a year and a half ago.
