Funny. I didn't know that Mark Twain ignored basic grammatical rules, such as not using real words.
Apparently he could have written this:
aginafnbnkn adfg a a g ehgi jaeflg aerg afg afg afg ag pjegj sadver[hprn hs dsgo[kep[gergpo[epfnskncs.

And I forgot to add that the time that elapses during processing doesn't even come close to being able to compare the syntax, grammar, word-choice and other claimed functions. It would probably need at least ten seconds to make a reliable analysis, but it doesn't even take half a second, hence no time to compare the text. You can live with narcissism and think that you're as good as Mary Shelley or Dickens, but don't try to defend yourself as a person of common sense for doing so.

Anyone who believes this program is consistent is either an idiot or in denial. Just face it for crying out loud! It's a sham!
I pasted a text from one of my stories and got Charles Dickens as a first result, then pasted the same text and got H.P. Lovecraft, who still doesn't remotely resemble Dickens.
Besides, there's no way an author can be similar to like ten different famous authors. I've gotten James Joyce (yeah right!), Rudyard Kipling, Vladimir Nabokov (strange since I don't write in Russian) Stephanie Meyers and Dan Brown. Gee, wonder why?
