Nothing's stopping you from using whatever method you'd like to use to judge the levels; however, using such a method to solve the levels is considered cheating. There's no requirement to actually solve each level before you rate it; however, I think a good rule of thumb is to play the level until you are confident that your opinion is informed enough to rate it. It sounds like you're already doing that. If you have to resort to cheating in order to solve the level, though, then it sounds like it's not too hard to decide what the rating would be, especially given that first-time players won't necessarily have an editor in front of them with which they can make such adjustments or look at the entire map.
