However, this seems to be a moving target. Every time I look at this, the level up time moves further away.
From the help articles:
To minimize the amount of waiting you do in the early levels, we recommend you do all your Lessons and Reviews as soon as they’re available.
I’m doing all the lessons and reviews the same day they appear, but I’m not doing them EXACTLY when they appear. Because of work, I sometimes do them a few hours later. Could this be the cause?
If so, is there a user script that will let me know how long until the next review in minutes/hours? The Tsurukame app has something that says exactly this but I’d rather not use yet another app. I want to keep things simple. If this info is available in WK great, if not, no big deal.
I don’t have such a user script so I can’t tell you how your script works. But I can tell you how WK works. Based on your screenshot, you would level as shown ONLY IF you pass ALL of your apprentice items as they come due. If you do reviews late or if you get apprentice items wrong, then your schedule will be pushed back accordingly and that is why your level up date/time keeps moving later in time.
The bottom line is you have guru 90% of your kanji in order to level up so if you keep getting enough apprentice items wrong or keep putting your reviews off, then your level up date/time keeps moving down the road. Hope this helps!
I think the other thing to note is that this is fine, in the grand scheme of things. The review intervals start at 4 and 8 hours, so the “ideal” (especially if you’re trying to go fast) is a schedule that says “do lessons in the morning, then review 1 4 hours after that, then review 2 8 hours after that” (there is discussion in the “ultimate guide” post about that). But somebody did some modelling of different numbers of reviews a day, and if you can do WK at least twice a day that isn’t that much slower overall than the theoretical optimum. And the in practice limit on speed for almost everyone is “how many reviews do you really want to do a day?”.
Since WK goes by hourly schedule, the script is likely to follow the same pattern, as it gets that data from WK. So, if you do not follow the hourly pattern yourself, the script will be off, as it does not know about your schedule. Further, you are unlikely to get everything right all the time (which the script probably is based on), and the script has no way of telling how many errors you will be making in the future.
