Though I think I probably already passed the hardest hump in Wanikani - that is to say, when you start getting a bunch of burn reviews in addition to all the other reviews. That happened for me around level 26 or 27, though; I went down to about a month a level. Now, though, I’m at about 9 to 11 days per level.
I feel like it’s going to be pretty much this level of review burden until I finish. Am I right?
