Hello!
A week (or a bit more) ago I’ve been at level 2 with the number of pending lessons at around 30-40 (been doing around 5-10 lessons a day, depending on their type). One moment I saw that the number of lessons is getting close to 10 and I was, ehm, happy? Then I did 5 reviews and wanikani decided to boom that number of lessons to 100+ at once, there I got to level 3.
I started doing 15-20 lessons a day, now (after around a week) nearly finished everything. Usually, I’ve been doing not more than 20-30 reviews a day (and the number of pending reviews was never more than 20). But today there’s been boom #2 — got 70+ reviews at the same time.
I assume that’s gonna be even hotter with greater levels, so just want to know what to be prepared for: assuming that I do 15-20 lessons a day and do all my reviews in time, what are the “okay” numbers of pending lessons/reviews at higher levels (10+? 30+?).

I’d feel better when I know that I do everything okay and that wanikani will not force me to commit suicide tomorrow by telling “yo, wanna do some 99999 reviews in the next hour? or maybe 66766 lessons?”
p.s. sorry for many letters, I didn’t intend to

If you do all of your lessons in big batches, then they’ll always come back for review in really big batches, which gives you horrible spikes (some people don’t mind, but I’d rather smooth them out as much as possible!).
