There’s some level of proficiency (whatever the percentage is) where each sentence is understood save for one word, and that word because of a single character that you can then look up in a dictionary. To me, that’s a useful level to achieve, because it means that you don’t have to constraint-solve sentences by guessing at the meaning of one character to decode the meanings of others, but instead can just hold onto the complete sentence minus one “hole” in your mind while you go look that “hole” up. Much less mentally-taxing!
