We think that with just a little extra marginal effort you'll remember those details - the entire body of knowledge - for more like a year. That's the benefit of exponential returns. But the prototype hasn't been out long enough to test that.

That is, the marginal review time is going down, even though the time between reviews is increasing exponentially.

All very preliminary, of course, and there are many significant issues (esp. selection effects!) which we're working to address in other ways. Still, it's encouraging!

Of course, "everyone who sticks with it" is a significant caveat. Maybe people who aren't going so well give up? We're investigating whether that might be the case or not.
