Another Retreat

<10kB. Updated 2017-08-26. Supports both Anki 2.0.x and 2.1.x.


Another Retreat: an Anki addon sets the next interval at lapse to the last succeed interval. Note: This add-on works with both Anki 2.0 and Anki 2.1, however, doesn't support V2 Scheduler. This addon changes the next interval at a lapse in the review to set the last successful interval. However, the default setting is a restart from one day no matter how familiar we were with the question at the previous review. Since 0.3.0, activation required on the deck option. Model Diagram for this addon handling Figure 1. Before: Default scheduling Figure 2. After: Another Retreat introduced How this addon works The User Manual describes how Anki handles a card at the lapse as follows. -------- Lapses When you forget a review card, it is said to have lapsed. The default behaviour for lapsed reviews is to reset the interval to 1 (ie, make it due tomorrow), and put it in the learning queue for a refresher in 10 minutes. This behaviour can be customized with the options listed below. If you leave the steps blank, Anki will not place the card back in the learning queue, and it will be rescheduled as a review with its new interval determined by the settings below. Note The new interval is determined when you answer "Again" to a review card, not when the card finishes its relearning steps. For this reason, the "Good" and "Easy" buttons during relearing do not alter the interval again - they only control which step you are on. If there is only a single step (the default), the "Easy" button will be hidden, since it would accomplish the same thing as the "Good" button. If you have 2 or more steps, "Easy" is not hidden, to allow you to graduate cards from the queue before all of their steps are finished. (From Lapses section in Anki User Manual) -------- This addon replaces 1-day interval (by default) for the lapsed review after the relearn session with the last successful interval. In fact, the interval appears with buttons to graduate the relearning. By default, the addon assigns the interval to "Good" button in relearning (1 step "10 minutes" in relearn). And you can skip the relearn session to change the deck option setting for lapse as below (no step in relearn). If you use 2 or more steps in the relearn session, the addon allocates the interval to "Good" button at the graduating step, and "Easy" button at each step (over 2 steps in relearn).

This works great! Does anyone know how to enable this add-on on filtered decks, though?

Good! Thank you

Works a treat!

Useful add on, but still buggy - the adjusted time interval sometimes appears as the 'good' option, and sometimes as 'easy'.

It is really good add-on. The lack of this functionality in Anki was the reason why I started to develop alternative for Anki

I appreciate this concept for hacking the scheduler to modify lapse behavior. My perception is that this decreases workload without increasing forgetting for young cards, while a better option for mature or "very mature" cards might be setting the "new interval" option to a non-zero, experimentally-determined percentage. This raises the question of whether a lapsed young card is truly a lapse or if the default learn behavior should be tweaked so that cards don't graduate so quickly (or whether this just reflects a bad habit of "memorization without learning").

I recall reading something recently that essentially said (paraphrasing) "difficult recall is desirable" because it improves retention. Another Retreat may be accomplishing that by improving the chances that the next recall will be more difficult compared to the default lapse behavior.

P.S. I would be in favor of Damien doing some fine-tuning of Anki's scheduler or at least optimizing the default settings in the next major version. Maybe incorporating this add-on to Anki's code would be one way to accomplish that. I don't know if there's strong evidence out there for improving the memory model (and I have no idea how evidence-based the newer SM algorithms are), but I'm in favor of Anki making more progress in this area.

I like this add-on a lot. Really great add-on.

However, I would caution: It did not work for Anki 2.1 with v2 experimental scheduler.

I switched to Anki 2.0 recently so that I could use load balancer (that also did not work for me on Anki 2.1 with v2 experimental scheduler). Another Retreat works perfected on Anki 2.0, therefore I am sticking with this set-up for now.

Great, especially for dealing with half-forgotten cards. Can use options groups to enable it for some decks and not for others.

An excellent, underrated add-on which has reduced my review load without a significant hit to my true recall rate.

Another Retreat (at lapse) review

This addon is really good. It removes the need for reviews at a time when they don't help much with remembering. This addon lowered my study time quite a bit, but it did not worsen my ability to recall cards. In addition to that, when I did not understand something about the mod, the author explained it to me in a very friendly way. I really want to thank the author for making this.
