I don't know anything about the nature of readability of texts
I want to know everything about ways of using the computer to determine readability that will be useful for me
No, readability statistics do not confirm my idea.
For example, I can choose some lexico-grammatical features such as the usage of about and check how is about used in my concordance. Is it used after a word or before an adjective etc. In other words I would learn the features of about and also teach my students. I may use the same sentences from the concordance to give my students some practice.
