I'm not really sure how the scheduling works, but my impression is that "so-so" means "reschedule it at the same interval". How does this work when we're practicing a word and get a single character wrong?
Just now I was practicing a multi-character word that has a rare character in it, and that word is the only place where I study that rare character. I got everything right in that word except the rare character, which I completely forgot how to write, and Skritter marked the word as "so-so". (This mostly happens to me with words of more than two characters; it seems like Skritter marks the word as "so-so" if I get a certain proportion of the characters right.)
Now, if the word is marked as "so-so", doesn't that mean it's rescheduled at the same interval? So, if the word was last studied 6 months ago, won't it be rescheduled for 6 months from now? And if that's the case, how will I ever learn the rare character? Or is there some kind of special logic that applies when the word is the only place where we're studying a character that we got wrong?
