Knowing 80% of the words in a text doesn't mean you understand 80% of its meaning, that is, you probably wouldn't get high marks on a basic comprehension test. I've seen some studies that indicate you need to know at least (around) 95% of the words in a text in order to understand it "enough" of it. (I don't have the links right now but could look it up at home if you're interested).
