Hi,
I just took a look all the way thru my vocab with the viewer. I discovered that... I have 3513 items or elements. And no life. Also, the viewer kind of sucks. The only key feature to improve is that it should sort both ascending and descending on the fields. But paging thru 3513 items 20 items at a time is no fun. Yes, see above, re my life.
Now, for those still with me... I have a handful of items that aren't scheduled to come up for more than 5 years, some as long as nine years. Admittedly, these are mostly characters that appear in other words, but I kind of think that the SRS algo is pushing these repetitions out pretty far, pretty fast... I mean, I've only been using Skritter for about 5 months, and it has decided that I can likely remember something for 9 years!? I think the algo should be tweaked so that the interval grows more slowly once it gets past, say, 2 years, and it should have some sort of asymptotic limit out around 5 years. I mean if you want to keep vocabulary knowledge forever, reviewing it once every 5 years doesn't seem like to much to ask.
Of course, tweaking the algo for how it handles my study schedule in 2014 may not be at the top of Nick's to do list...
