True Retention

Description

NOTE: In modern versions of anki (2.1.33 and newer), you ***MUST*** open the Stats window by shift-clicking in order to view addon-based stats information. If you do not hold shift, a different stats window will appear where addon-based stats ***do not display***. This behavior is ***covered in Anki's documention***. Adds a few new lines to the Statistics window, including True Retention (pass rate calculated only among "Review" cards) and a few placebo stats. "True Retention" is a better indicator of learning quality than "Again" rate. Hotfix: Round %age to one decimal point (same as Anki's "correct rate") Update: Added more time periods. Update: Already supports Anki 2.1.x but have to upload a new file for it. Yes, the license of this addon is the same as the code it originates from.

Good! 😋

I don't really use it that much, but it works as advertised, I can't deny that.
on 1625214471
Not working on the latest anki version. I hope the developer updates it soon!
on 1624427746
Does not work on 2.1.35 even after using shift + stats. Shows everything else except retention :(

Edited: it works now 1 month later with true retention showing up, still waiting on supermature rate.
on 1621532762
Does what it says on the box.
on 1620841026
Useful add-on to help me adjust intervals for my decks, thanks!
on 1618742325
I don't know if it helps but this add-on only worked once I restarted the app and shift-click stats. For those who didn't find it show up, you may try this to see if it works.

Guys, PLEASE shift click ie hold down shift+left click on 'stats'. PLEASE
on 1612736364
Nice, thank you :)
on 1612464451
It's one of the most useful add-ons I've ever tried.
on 1608538528
good
on 1608352250
Useful numbers to see :) Thanks!
on 1607767109
Useful.

EDIT: Oh, man. You need to hold shift down nowadays to view the old stats screen to use it. Sometimes it feels like anki goes out of its way to break every addon when it updates lol
on 1606786919
EVERYBODY WHO'S GIVEN A THUMBS DOWN:

PLEASE READ THE FIRST LINE IN THE DESCRIPTION SECTION.
on 1605202202
it doesnt appear on mys decks, dont know why
on 1604787941
the new update ruined the stats, this is so helpful as it brings the old style back when shift-clicking
on 1603039934
Shift + click to go to true retention stats on anki version 2.1.33
on 1602364840
Works
on 1599715486
works well!
on 1599568772
Works great, but it does not work on 2.1.33
on 1599283696
It does not work on 2.1.33
on 1597174474
Shit + click on stats does work.
on 1597012034
Pressed shift while clicking "stats" as people suggested below. Still shows "0" or "N/A" for the stats. Not working.
on 1596933975
Can confirm that holding "shift" + pressing stats button at the top (next to browse/sync) does work.
on 1596672809
This works fine with the latest (2.1.29) anki desktop; hold down "shift" while you hit the "stats" button.
on 1596363527
Out of date in the newest versions. Don't update Anki unless you don't mind losing this addon. I'm disappointed, because I used this every day.
on 1595866404
Doesn't work in a proper way starting version 2.1.26 of Anki when you want to see the stats for a deck life. It seems it hasn't been updated in a long time which is unfortunate because I really liked the addon. Hope the developer of the addon is going to attend to this issue.
on 1595789885
Unfortunately doesn't work for me anymore since the 2.1.28 update.
on 1594932045
Could use some documentation. What is "supermature"? What are "placebo stats"? What is counted in "passed" and "flunked" reviews? Hard to know how to interpret this stuff when it isn't defined.
on 1594783064
Great addition.

on 1490400000
Howto use this add-on?

I have search for many days and I haven't find any instruction about how to use these add on can any people teach me(by PrtScSysRq) thanks.
on 1474416000
Better than you think

Usually, my True Retention is better than my Again count. It shows that I do much better than I would have thought otherwise, which really helps with motivation.
on 1463702400
Interesting.

For me the more statistics the better, the more control and more insight into the learning process I have.
I wish there was a year and a deck life true retention. It would be great if users could edit and set there own true retention standards. I invite you to a discussion:
