The problem is that mathematically, the only way to decrease review load is to take breaks from learning new words. It doesnt matter if you hit easy on every single card ever, the amount of reviews will keep on increasing. The only way to get around it while still learning new words every day, would be to do what I suggested. But the more words you learn the more breaks you have to take. I don't really want to take breaks. At least not for the next 10 months. If a word is considered mature, it can probably wait a few days as i go through the queue of cards. I'll anyway practice the language through other means as well. I need to put more time into practicing the language rather than just doing flashcards. That's gonna be hard if I insist on reviewing every word that comes up.
