Sorry to post here but the mods for GT read this as much or more than emails...anyway I think the STL system needs to be updated. From what I'm seeing, the algorithm uses your 'score' for a specific card for a subject and then calculates how long that card can be viewed again. One problem with this, which is a rather big problem, is this: let's say you're viewing a card you knew very very well...5 months ago. Well you probably racked up a really strong average, probably between 4-5 over a number of views. So if you forget something, and answer at say a 1-2...that 1 or 2 doesn't impact the average enough to change the study of the card, it's still viewed as 'mastered' and the next time you see the card is 10-12 days (from what I've seen). This doesn't make sense to me...if you don't know the card, it should come up 1-3 days after, regardless of your average score. The programing for this wouldn't be too intense, just add some if statement along the lines of if already at +4 average, "mastery achieved", and answer "1-2" then reset the mastery or something like that. Otherwise, the cards either get regarded as 'mastered' or you have to manually update your study schedule (which is annoying and defeats the purpose of purchasing a program that's supposed to do that for you). Just a suggestion and I hope the guys read this for the next crop of people to use their program.
