I finished uploading the vast majority of my vocabulary a couple of weeks ago. At that time, I had it set at 92%. Since I had already studied the words, I was content with that. Seeing as I was starting to study new words, I decided to crank it up to 95%...

Big mistake. I now have a queue of 700 plus actions a day and still growing....

救命！救命！

I recently went back from 97 to 90 or 92 and have been breathing much easier lately and have started adding a bunch of new words. I never really thought that setting had much effect as my retention always hovered around 90% even when I was aiming for 97%, but my queue has pretty much halved if not more.

I'm glad I stumbled on this thread. I think I might crank down my retention target as well. I've been finding it hard to keep up with all the reviews lately.
