Mastery
Mastery is the number Kyonote shows for a notebook: how much of it you've actually proven you know. It's a ring rather than a score, because it's a picture of coverage, not a grade.
What the number is a percentage of
The denominator is the ideas in your files — fixed when the file is read. It is not the number of questions in the pool.
That distinction is the whole design. If the number counted questions, then generating more questions would push your percentage down, and the app would be punishing you for the one action that helps you learn. Counting ideas means making more questions can only ever help.
Ideas you haven't been tested on yet stay in the denominator. That's on purpose: a notebook isn't 100% because you got your one answer right.
Why it doesn't reset
Changing difficulty doesn't wipe anything. Mastery isn't a stored score that gets recalculated — the only thing Kyonote stores is your answers, and everything else is worked out from them. So there's nothing to reset.
Reaching above the level you've proven can raise your floor. It never lowers it.
How to actually use it
- Chase the empty part of the ring, not the number. The gap tells you which parts of the notebook you've never been asked about.
- Don't grind one file. Coverage moves when you touch material you haven't proven yet.
- Expect it to dip when you add files. More ideas means more to prove. That's the number being honest.
Pair it with the other tools
- Practice is how the ring moves.
- Your activity shows the effort behind it.
