200-300 new words a day?

Over on the medical school Anki subreddit they talk about how its possible to learn 200-300 new cards per day. https://www.reddit.com/r/medicalschoolanki/s/QjGUTIAN85

Those are not just words but medical facts and qeustions so it should be way tougher to study compared to words which is just one symbol. If its possible to learn so many new medical cards per day would it be possible to learn 200-300 new Japanese words in Anki per day? Would it be sustainable? If not, Why?
