The first bar gives you an overview of how much you still know.
The bar shows you the probability that you still remember the content of a lesson.
If there is a 10% probability that you remember the complete contentor a 100% probability that you know the first 10% of the materialdoesn't make a difference here.
The second bar tells you which parts of the lesson you still remember.
The bar shows how your knowledge is spread over the pages of a book, the flashcards of a cardbox or the lessons of a course.
The greener a section the more you still know about it.
You haven't started reading yet so you don't know anything about the book.
Immediately after you have read the first 100 pages you remember the things you read quite well.
Three days later you have already forgotten a quarter of the things you read. The quality of your knowledge about the first 100
pages declines -- and the color of the lower bar slides into some reddish brown.
On the other hand you have read 50 more pages and gained new knowledge. Since it took you three days to read the
50 pages you remember more about the last few pages than about the first pages.
Again three days pass, again you forget part of what you read.
Using the notes you took while reading quickly you repeat the first 100 pages and refresh your knowledge about it. Your knowledge rises to 56%, the first 100 pages look all green again.
Three days later you have forgotten some details but the more often you repeat the slower you forget.
Finally you read the remaining pages of the book. Mindpicnic estimates that you remember about 80% of the content. The second bar tells you that the gap's in your knowledge are mainly around pages 100f.
A few days later you have forgotten some of the things you read last, too, so you decide to repeat pages 100-150 first, then the whole book.
Now the repetition is done and your knowledge is excellent. Mindpicnic takes care of keeping it this way.
As soon as your knowledge sinks under 92% you will see a reminder on your Learn page to repeat the book.
