The leaderboard that shows after a quiz and that you can put as a widget on the dashboard isn’t working correctly. When I have selected ‘the last month’ (rather than the last week, all time, etc.) it defaults to the category ‘correct answers’ (rather than correct vocab, 好 point, etc.), which is normal. But then it says I have 0 correct answers, which is untrue, and then when I try and switch from correct answers to 好 points, for example, it doesn’t allow this and switches back to correct answers, with me still at #4500 with 0 correct answers. When I switch to the last week page, it shows my actual correct answers, but still doesn’t allow me to switch to other categories. Same for the last six months and all time.
The leaderboards data is such a mess - in that it takes an hour to re-run the data just once, and usually, when re-running it, *something* makes it so that the bug disappears (I've never been able to replicate the bugs that come up on re-running).
I will try looking into this soon, but it is intensely frustrating to fix :(
Yea, so I think you've actually uncovered an undocumented bug. While renshuu does hold onto a full set of quiz history for each user, scanning that when doing leaderboard stats is far from ideal. So, each term has a summarized set of "# of times correct", "# of times missed", etc. These are used for your historical stats. The way it get the stats for the last month is to total all those up for now, and then subtract the same totals from a month ago (so you get the difference across the month).
The issue is that when you reset a schedule, it not only wipes your mastery data, but it also wipes these summarized quiz result counts. Those numbers are not just used for the leaderboards, but also things such as "has this term been quizzed before", and "what is their ratio of correct to incorrect"?
So, when you wiped it, a chunk of the grammar data for the leaderboards vanished :(.
There is not really a good way to fix this without significant changes to a number of logging systems, so this may have to remain unfixed.
), just not on the dashboard itself.
