Introduction
Anki Revlogs 10K is a dataset of 10k collections from Anki for FSRS project. It is a random sample of collections with 5000+ revlog entries, so it should contain a mix of older (still active) users, and newer users.
The dataset contains three parts: revlogs, cards, and decks.

- state: Card's learning state (0: new, 1: learning, 2: review, 3: relearning)
- duration: Time spent on the card review in milliseconds (range: 0-60000)
