I've been using Pleco's flashcards (v 3.2.60) for a couple of months now, in self-graded SRS mode, and have been adjusting the scoring parameters a bit. One thing I was hugely confused about was the headline "Incorrect score decrease %". I've been assuming that it does what it says, but after experimenting with backups, I realized it should actually be named e.g. "Incorrect score factor %", since if F is the configured factor for the quality of your answer, and S was your earlier score, the new score S' appears to be calculated as S'=S*F/100, rather than S'=S*(1-F/100) as would be expected (unless F=0, in which case S'=S, or S'=max(Minimum Score, S)?)
I was wondering why it seemed my near misses were heavily penalized, whereas complete failures didn't make the cards appear much more often. I had 20 % configured as a supposedly moderate incorrect score decrease for "Almost remembered", so the scores got whacked down to a fifth of the previous ones...
However, "Correct scale score increase %" *seems* to be calculated as (approximately, depending on easiness, I assume) S'=S*(1+F/100).
Am I correct in my observations? If so, perhaps you should consider changing the text.
