So from the sound of it, you are always hitting 100% correct scores, right? You review the lesson if you get one wrong, but still mark it as correct.
For me, not all words are equal in difficulty. I can take one look at breakfast and think to myself, morning meal, makes sense, and because I know morning and meal, it requires next to no review. It comes in up reviews and I get it right instantly, takes under a second to type in, and I move on with the tiny bit of reinforcement.
Now, joushaken, boarding pass, took me ages. Not sure why, but I had it being reviewed twice a day for over a week and it still hasn’t completely sunk in. If I can’t come up with the right answer within about 5 seconds, I know I need more study, so it gets marked wrong and shows up again sooner. Even if I get close to the answer, say kaisha instead of kousha, I still mark it wrong, because for me the goal isn’t to get the words marked as expert on bunpro, but to be able to have the right word pop into my head instantly.
I use wanikani without any addons, and give myself a 5 second time limit on each word, which means sometimes I do typos on words about to be burned, or just have a brain fart and put in the wrong answer when I know the right one. That hurts, and it’s a shame to see the words take an extra 4 months to burn when that happens, but for me, it’s worth it.
If you feel like you are happy with your current state on a word, keep it marked right. If you are not happy, mark it wrong.
Hope that helps.
