How to use forgetting in your advantage
A quote from the Anki page seems to be:"Remember Efficiently: Only practice the material that you’re about to forget."I, however, don’t think being unable to recall something is a bad thing  per se.

Why not? Well, there are essentially two components of memory: Storage strength and retrieval strength.

When you are unable to recall something, it probably means your retrieval strength wasn’t “strong” enough. The storage strength, however, could have remained almost stable since the period you first learned something.

This means that when you relearn something, you aren’t exactly “starting over at zero” (i.e. the storage strength is still present). This is also why many Anki users recommend setting “New interval” to anything other than “zero” (I put mine at 70%):

Taking Advantage of Forgetting
One way I try to take advantage of forgetting, is that whenever I forget something, I try to add more “depth” and “analysis” to it i.e. deepen my understanding so that both my retrieval and storage strength go up.

This is called the “levels-of-processing effect”:"The levels-of-processing effect describes memory recall of stimuli as a function of the depth of mental processing. Deeper levels of analysis produce more elaborate, longer-lasting, and stronger memory traces than shallow levels of analysis."There are essentially two ways of making you recall something before forgetting: Let’s take an example of a card of mine:"Question: Entorhinal cortex main function""Answer: Main interface between the hippocampus and neocortex" That is exactly what this Anki addons does:
 * 1) Shorten the interval period, or;
 * 2) Trying to understand your “cards” more.
 * 1) I could try to memorize this without any understanding of what the functions are of the “hippocampus” and the “neocortex” nor the concept of “systems consolidation”. The consequence, then, is that the interval time between each spaced repetition becomes rather short due to a lack of understanding (levels-of-processing effect), or;
 * 2) I could also try to put an interval time long enough that I will forget it X% of repetitions, forcing me to deepen my understanding each time I forget the answer as well as to increase the interval time, but short enough that it doesn’t cause a huge drop in storage strength.

I personally put my rate of forgetting at 80%, see the video linked above for the reasoning.
