Such a soft reset would really mess with the scheduling of words and, provided that you haven’t kept up with the vocabulary outside of Skritter, lead to a drastic decrease in retention rate, which would in the long-term lead to even more reviews.
Some things to try:
- Ban things you already know well
- Don’t add things unless you really need them
- Set a high but reasonable goal and start chipping away at the queue
- Ignore the total due count and study selected decks (the select more and more decks as you get them under control)
