As long as you are determined you will be fine!! Keep doing those reviews and pushing forward!! 頑張ってね 
Nothing is impossible. When I was 30+ lvl and I was obstructed from doing reviews for around 2 weeks I just dedicated around 5 days or so to clearning up the review pile of 1000 items. Just do as people say: abstain from lessons and attack that pile. Do 200-300 a day at least if you want it gone quick enough.
That graph is based on the data of forum users from one year ago 
@BIsTheAnswer made some new updated graphs on the distribution of forum users’ level, two weeks ago.
OP this may or may not help but I find taking a day off during the week really helps. I might have some exposure to Japanese on that day (through something like Stardew Valley or reading some of a book) but Wanikani, Anki, and JLPT grammar are off limits. It can help to build up steam for the next week.
I want to specify that I have clearly said I have found various negative things about WaniKani but I have never said that it is bad or that all in all I do not like it.
I am of the opinion that there are no infallible methods and that to date no method has worked better for me, despite everything.
Complain about paying? I’m sorry … but that’s right for me. I’m not doing bad reviews and to anyone who asked me I always said “this software, TRY IT”.
My complaints are due to the fact that a software must be flexible (I am a programmer, I understand the difficulties) and since WK is at an excellent level, perceiving that there are people behind it and not robots could be an additional step. It is a suggestion that comes from stress and maybe I expressed it directly but I never wanted to create any situation of personal insults.
Thanks to everyone for the help.
Thanks to Admin for stopping by.
You’re right, that was stupid of me lol
