Privacy pro-tip. Don’t use a highlighter function to conceal sensitive information. (Fortunately all of this info is harmless and you should be proud of your progress)
I like how they do it. If I don’t want new reviews after 9pm, generally I just need to stop doing reviews after 9 pm. Then very few will appear. When they appear I often feel pressured to do them even if I don’t want to.
Wanikani’s system is just (last reviewed time + (new SRS Interval) -1 hour) rounded down. So if you complete it at 8:30PM, it’ll be available at 7:00pm on it’s due date.
I think Bunpro doesn’t round down? Don’t quote me. But it’s a pretty minor difference. Just looks like you normally do your reviews in the morning to me.
