Hi everyone - strange request, but has anyone implemented a ���space based repetition��� algorithm in Pharo/Smalltalk? Before going and implementing it for a little flashcard program for my daughter, I thought it might be worth checking as while it will be fun to implement I fear I may end up getting distracted on the wrong thing���

I���m after something addressing this: https://en.wikipedia.org/wiki/Spaced_repetition (possibly SuperMemo SM-2)
