"Words are automatically added from lists you have activated while you practice. By default, they start being added as you finish up all your due items, but you can change it to add words earlier or later, or turn off automatic adding completely."
I have over 1700 words left to review.
I have my own little challenge algorithm where if I get ten prompts right in a row I can add a new word.
I'm surprised, however, to find that the Skritter algorithm is _also_ adding new words right now.
Is this because most of the words in my queue are words that I know? Or is this a glitch?
