Database Internals
A fact counts as mastered once its review interval reaches 7 days — you have recalled it correctly enough times that it is not due again for a week — and, where it has an understanding question, you have passed that too.
| proficient | 0 | |
| practiced | 2 | |
| learning | 5 | |
| unseen | 67 |
36 facts still to master, needing about 87 reviews between them. That count comes from running the scheduler forward over each fact's own state.
| Pace | Time | Finish |
|---|---|---|
| 15 min/day | 15 days | 2026-11-01 |
| 30 min/day | 14 days | 2026-10-31 |
| 60 min/day | 14 days | 2026-10-31 |
Assumed, not measured: 25 seconds per question. After 20 timed answers this is replaced by your own pace — so far there are 19.
Every finish date includes about 13 days of spacing at the end. Reviews have to be spread out to work, so the last facts you meet cannot be mastered sooner however long you study each day.
