Most of the time if you know something better you can answer it faster and well I experience this a lot whenever I review kanji I know or revisit hiragana/katakana once in a while to make sure I got that 100%.

Either way this is a great idea to include as many books/resources forget to explain these simple phrases.

Read The Kanji is trying to determine the memory strength of a word by the number of correct answers. This is inefficient. Only the user knows this. There needs to be a mechanism where the user can determine the strength of a word. e.g. check box that means: I know this word very well today and I don’t want to see it another 20 times today but I want to see it tomorrow. Or like Anki, have selection of “Again”, “Good” “Easy” “Very Easy” to determine next review interval.

Well that’s my 2 cents! This is a great site! The physical act of entering the answer is the big difference over flash card systems. Thanks!

There are two reasons why cards should be randomized globally instead of locally. The first is false context. If the cards always show up surrounded by the same other cards, then I will learn them based on their location in the deck and not the kanjis themselves. The second is memorization value added. Seeing a card 20 times in a row does less for memorization than seeing a card 5 times with increasing distance between them. This forces the memory to stretch from short into long term. This is already being addressed somewhat with the word strength, but the actual randomizing of the cards is what helps with memorization.

A suggested algorithm is the following:

Assign each card a weight. Cards which have never been seen are assigned a weight of 5, for example. Each time the card is answered correctly resulting in an increased word strength will decrease the weight by 1 point. The deck randomizer then draws a card with even probability over the weights so that a card with weight 5 is five times more likely to be drawn than a card with weight 1. A time lag can also be inserted into the algorithm so that after a card has been answered correctly it is not seen again for X number of draws before being returned to the deck with its updated weight.

The repetition factor can control how many times a card can be drawn before it is put on hold with 0 being one time and 10 being, say, 10 times.

Thanks for all the hard work! Look forward to seeing what’s next.

however i’d like to point out a sort of bug in the combo system. i’m working on repetition level 2. if you get a card wrong *once*, it comes back into the deck until it’s yellow. if you get it wrong *twice* before getting it right, it comes back until it’s light green. this means that the card that you know less well is actually labeled as stronger!
