Estimated Total Knowledge graph over time

It seems unlikely that Knowledge Over time will make it in Anki 25.06, but I’m hoping for the next 25.XX release.

I’m also looking forward to the implementation. But with each new graph, statistics are becoming less and less convenient, and anki still does not allow you to sort graphs.

It might also be a good idea to redesign that page, e.g. by creating a tabbed view. Each tab would be a category, grouping related graphs into a single page. E.g. there could be a Card Stats tab, grouping Card Stability, Card Difficulty and Card Retrievability together.

Such a view would also allow to have a tab called Favorites or similar, so that the user could pin their most viewed tabs and view them at a single place.

On Desktop, the tabs could be shown e.g. on the left side, similar to the entries in the Browse screen (but much more organized and less cluttered). For mobile devices, the tabbed view could be reduced to a button (like a hamburger menu), which would allow to select the tabs on-click.

I think a better option is what the current template editor does for card types. Swiping left and right to switch between tabs quickly.

Hello everyone,

I just came across this discussion about the feature request for ‘Estimated Total Knowledge over Time’. I found it very interesting!

I’ve developed an add-on called ‘Accumulated Retention Graph’ (available at https://ankiweb.net/shared/info/1971437351 ). Doesn’t it offer a similar view to what you’re discussing, showing the number of cards by state (Retained, Mature, Young, Learning) over time?

I’d love to hear your thoughts and how it could fit in or contribute to this discussion. Any feedback is welcome!

Judging by the description, your addon just shows the number of cards. That is, it does not take into account their R.

Estimated total knowledge is the total number of cards you are likely to currently remember, calculated by multiplying average retrievability by the number of cards that have been reviewed at least once.

If you have 100 cards that have average R of 50%, that means total knowledge is only 50 cards. That’s what we are talking about.

I understand the importance of Retrievability (R) and how it differs from simple card counts. I’ll study the calculation and, if possible, integrate this metric into my add-on. In the meantime, perhaps it can be useful as a temporary solution.
Where can I find a more detailed formula for Retrievability to assess its implementation?

As I mentioned in my original post, this feature is already implemented in Luc’s Search Stats Extended add-on.

This add-on already does it: https://ankiweb.net/shared/info/1613056169

Thanks for the observation! I opened Luc’s Search Stats Extended add-on and saw that it indeed offers many graphs. It’s excellent, but I’m not sure I could use it for gamification in the way I’m looking for.

My focus with my add-on is precisely to gamify progress on the main page, in a more direct and visual way, as in the graph I implemented:

I will still analyze the Retrievability formula correctly, but I don’t want to derail the main focus of the discussion, which is the native implementation of this feature. I appreciate your understanding and for keeping the topic focused on the forum’s main goal.

I’m not sure what the difference between that and my add-on would be but if you want to include it in your own add-on because its cool (:smiling_face_with_sunglasses:) that’s fine.
I extracted the code for the memorised graph here: GitHub - Luc-Mcgrady/ts-fsrs-memorized. I still haven’t gotten around to finishing it but it should work as it does in SSE.

I’m not sure if your add-on uses JavaScript but if it does i hope this helps.
