My daily rate of new cards is set to 50, which explains why the number of unseen cards decreases with ~18 000 per year (50x365= 18 250, barring days when I'm travelling, or if just miss my reviews).
The number of mature cards increased more in 2019 than the previous years - this has to do with how well I know the cards that are thrown at me. Who knows, maybe I (finally) absorbed sentence patterns and vocabulary and gave myself a higher grade on those cards.
The number of young+learn cards increased with ~1800 in 2019, then dropped to 1020 this year. Vocabulary learning isn't static/linear/predictable, hence the difference.
Portuguese is 100% based on a Tatoeba deck, Esperanto is a mix of manually added content and Tatoeba, and that also applies to Mandarin (I think).
