or get the wanikani ultimate timeline script that someone made for wanikani. It shows me exactly when each review will be. Shortest time to level up, perfectly following reviews on this timeline is 6 days and 20 hours, but that is not usually practical for most people since it sometimes requires things like getting up in the middle of the night. People seem to suggest 8ish days a level for a good brisk pace and like 10-12 if you want to enjoy it a bit more. Good luck.
My confusion came from the Field “Time in Level”. I just “passed” into level four since Nov 1st (4 days ago) but it shows as if I was there since +70 days…
I understood now the logic behind the “Time to next level” but still guessing on the other two…
Some apps don’t detect next level until you do a lesson for your next level. But when you have a question like this, make sure you check the web site to see what it says there. If it’s not on the web page, this is a feature of your app, which are ALL third party.
