OK, so I read a couple chapters of Balzac and some other things in French on lingq, all of which falls under the category of literature, a couple weeks ago. Dividing words read by lingqs made, I got 315 words known to every unknown word. I guess that’s pretty good, considering it’s 19th century literature. If I were to read something from the 20th century I think I would know a much greater percentage, and my perusal of Sartre’s “Les Mots” which I have by my side seems to prove this.
Edit: Realized I calculated this differently than others in the thread.
