question about lapses

[Murat Sincan]

Hello,
Is there a way to know the interval for the most recent lapse? In
other words, I have this card that is quite hard to learn and I lapsed
three times so this is my fourth round trying to learn (after three
times grading the card with a zero or one) and I have seen this card
say, 100 days ago. I would like to know what was the "last repeated
XXX days ago" value was the last time I gave this card a zero or one
and told mnemosyne that I forgot it. This was I can track if I am
getting better or worse in remembering the contents of this card?
Thanks

Murat

That info is stored in the repetition history of Mnemosyne 2.0, but you will
need to write a custom sqlite query to get that data out...

Will you accept the code if I extend the "Current card" statistics to show this? Maybe add a "Detailed statistics" button to the page if there are more info about the card the people want?

You can write this code as custom plugin and put it on the website. So,
there is no need for me to formally accept this :-)

Have a look at the example_plugins dir to get you started.

   Tom, are u going to write that Plugin ?
I like this option and would like to add my 5 cents to your plugin.
For now, I extract this info from the Browser - prior to reviewing cards.  The process is:
- write stubborn cards on paper, like a spread sheet;
- Tag stubborn cards "stubborn";
- Go to browser; activate tag Stub;
- copy the "Last rep" number of days;  screen dump or on paper.
-------  Your plugin would give this ( and more ) stats on ALL cards.
Good stat would be
Retention score as a function of "Days lapsed".
The Intervals with less then 80%, would need to be shorten; there is a way to control that ( on a limited number of cards ); I am doing it now.
 
Good day.

I don't know. If I find time, and figures out how to use the db, I will. But I don't if/when that will happen. So don't wait for me, if someone else want to do it.

    Hi Tom.
Thanks for writing it.
How about adding my suggestion on the "Retention score as a function of "Days lapsed" ?
   I did not give you enough info; here it is:
It would be  --  more accurately named  -- the "Retention score for a set of Rep Intervals".
     Retention score   does reflect the memory dynamics. Lapses, on the other hand,   reflect the user's Grading 'wild guess' process.

An example of how the Retention %  would be used:
    Let's say, the Retention % for the sequence of    Intervals  of
    1day,  3    7    12      is 90%  and
    1               7    12      is 90% ;
 you can see  that the second Rep in 3 days is useless;  skip it;   save time. 
    I hope the example is clear.

I devised a method to utilize the Retention % info within Mnemosyne.

      So, would you please embed my request into your plugin.
Thank you.

PS.  I dont know if it concerns you, but..
After you said that you dont know when/if  you can do it,
I sent the same request { for Retention % } to another programmer;  there is no responce yet.

If I can understand what you are asking for, and find a way to do it, sure, but right now I don't have ha clue what you are talking about :-) You are talking to a musician that know programming and math, but I don't know very much about statistics, except simple terms like mean and median.

"Retention score" as I understand it, and as I (think) the "Retention score" statistics tab works, is the percentage of cards asked that the user recalled correctly. Is this right?

An example of how the Retention %  would be used:
    Let's say, the Retention % for the sequence of    Intervals  of
    1day,  3    7    12      is 90%  and
    1               7    12      is 90% ;

    I hope the example is clear.

      So, would you please embed my request into your plugin.

How would you  calculate "Let's say, the Retention % for the sequence of Intervals  of     1day,  3    7    12"?
Then I'm lost with regards to what you want the plugin to do. Do you want it to reschedule cards based on retention score? If so, this is more complicated than I want to do at this time.

A little clueless, but still interested,
