Hi,
I would like to see statistics for each collection based on time to next review.
For example, you can see in the picture below my old custom collection where I have mastered almost all words. The problem is the “mastered” category becomes useless as far as seeing progress goes because everything becomes mastered after six months. But I have words there that have next review in two years and words that have it in six months. And they all look like mastered.
It would be great to have stats for collections based on time to next review, for example (3to6 months: 10%, 6 to 12 months: 50%, 1 to 2 years: 20%, 2 to 3 years: 10%, over 3 years: 10%)
