I'll add this, if it helps. At one point a few years ago I reached 300 verses finished. But I believe there is an option, when you reach that point, to click "fully learnt" or to review them again in one year. I believe I chose to review them again, and so I had a similar back and forth as Luli described, where I reached 300, went backwards, then reached it again (several times). The rest of my story is that I at some point started using Memverse, then came back here and reset everything to zero :) At this moment I have a lot of verses in the 90 percent range, and hope they will be reaching "fully learnt" sometime soon :)
The thing I'm not clear on is this: isn't it possible to click "fully learnt", and then you won't be shown those verses for review, ever again? If anyone knows about this, it would be great if they could clue us in :)
To Worm, you don't have to go. I'm sure all would agree you are welcome to stay :) I say that because you wrote, "I'm going to use a paper system from now on."
