Thank you for these, Hine! I think I messed up the SRS times on my core 6k deck (some cards are like 4 months but I think it's only the second or first time I've seen them if I click good or easy! I think I saw 1.2years, once!!!) I definitely fiddled with the times when I first got the deck...
Well, not knowing what you did with the settings I would recommend that you start with resetting the options to their original values. If you want to continue to use my settings it will look like the following.
I prefer these setting to best replicate the intervals that WaniKani has. But there are a couple of things to keep in mind with this. First I am using the steps in minutes to bypass the Anki algorithm. This will mean that the cards will always need to be either in the New Card stack or the Lapses stack. You know you are in one of these by the buttons for choosing if you get the answer correct or not. There should only be three buttons. If there are four buttons then you are in the Anki algorithm.
The next thing to keep in mind is that anytime you press Easy you immediately push the card into the Anki algorithm. So, if you want to follow the steps in minutes you should never press Easy. Again or Good only.
For the cards that are already pushed out there are two options. First you can simply press Again and it will place the card into the Lapses pile and your next review for it will be 10080 minutes or 7 days. If that is still too far out your other option is to select the card in the browser and use the reschedule option to send the card to the end of the new card queue.
The only other thing to keep in mind is that once you graduate for the New Card stack it will automatically place you into the Anki algorithm. Again, you will know this when you see four buttons. Just press Again from that point and it will place the card into the Lapses stack and it's business as usual.
This is how I use it. I hope you find it useful.
