But rule 6 says not to apply rule 5 for failed cards: "If the quality response was lower than 3 then start repetitions for the item from the beginning without changing the E-Factor" I guess the reasoning behind this was that after a lot a repetitions, increasing the difficulty as well as resetting the interval was considered too big of a penalty. I agree in the corner case you mention (immediately failure), this seams suboptimal, but remember that this is not an exact science, and the idea is that after many repetitions and corrections by the user, the intervals and easiness factors converge to something which is roughly OK. I'm hesitant to change the scheduler now after so many years without detailed statistical analysis to back up any change. The data is there in the collected learning logs, but analyzing it has not yet made it to the top of my list. Anyway, thanks for your detailed feedback!
