I’m seeing the same couple dozen or so words over and over again, even though the timings say that I shouldn’t be seeing some them for days (ex: yi1/one keeps showing up even though I mark it too easy). Meanwhile, there’s plenty of words in my entire history that could be reviewed yet aren’t (right now, I’m in a review-heavy mode of going through Skritter Chinese 101 while adding in Radicals).
I feel like the algorithm needs to be a little smarter than it is. Some words seem to come up often and others hardly ever (and then when they do finally come up, I’ve forgotten it so I get it wrong so it enters heavy rotation). I’d rather a bit more evenness to the learning process.
Also, it’d be nice if there was a way to weight certain kinds of study over others. For example, I’d like to have writing practice occur more than other kinds of practice because I learn all the parts better through the kinesthetics of writing.
