I have been playing with 100 “new” words and getting about 250 “review” words for about two weeks now - but for some reason, I got only about 20 reviews yesterday and today it is sitting at 0 review words ready.
I know there is some up and down, depending on whether I pass a word, or miss it and it goes back down to 25% learned. But, how am I literally getting zero words to review with the last seven days showing 100 new words each day???
