Hi,
I'm starting with Skritter and I find it a really interesting application. I'm a great fan of spaced repetition (I've been using Anki for some while now), and I think it's great that Skritter uses such a system to choose which cards to make me review.
However, I have a remark concerning what the Fool's Workshop calls the "Insatiability Flaw" of some SRS ( http://foolsworkshop.com/reviews/the-insatiability-flaw ). If I don't voluntarily stop studying, skritter constantly prompts me to study more characters. There seems to be no way to know when I've been studying "enough". According to spaced repetition, one should review an item when one is just about to forget it, but skritter makes me review items I don't need to.
Am I doing something wrong here? Is there a way to study only those items which are due (with maybe new items also)?
