The 0/0 Streak Challenge

@Peyo For me - by around where you are, or earlier! (Maybe some never do?) I found that doing a max of about 25 lessons per day (prioritizing radicals to immediately and spreading kanji out over a few days*) was much more sustainable, personally. (It really evens out reviews over time, in addition to having a manageable amount of learning at a time!)

*this approach still allows leveling up in minimal time and clearing out lessons at least once per level, without having to take on everything at once. Doable via the lesson filter script ([Userscript] WaniKani Lesson Filter), which allows you to pick how many each of radicals/kanji/vocab you learn in a given session.
