The difficulty, of course, is that clarity is primarily a function of ideas and meaning, and ideas and meaning are totally opaque to tools like this. For example, no complaints about this sentence: > The poets breach the digestives by moatbutt every Thur. And if I change the sentence to: > The poets breach the digestives by moatbutt every Thurs. it tells me my reading level has changed from 7th to 8th grade despite Thurs being a much more common shortening of "Thursday" than "Thur", which is nonsense. God forbid such tools ever be used with young students.
