Queue burndown: how long until my reviews are clear?
You have been gone, the queue is huge, and you don't know if it's worth the effort to come back. This calculator gives you a concrete answer: at the pace you can sustain, here's the exact day your queue hits zero. Plug in your numbers, see if it's a week or a month, and decide whether to grind, reset, or use vacation mode.
Why accuracy matters more than effort
A 50% accuracy session does not clear half the queue. Each wrong answer demotes the item, which means it comes back sooner. Net clearance is roughly reviews_per_day × accuracy - so 100 reviews/day at 50% only clears 50 items net. At 90%, you clear 90. The accuracy slider matters more than people expect.
Practically: don't rush your recovery sessions chasing volume. A calm 50-review session at 85% accuracy clears more queue than a desperate 150-review session at 55%.
Why pausing lessons is non-negotiable
Each new lesson commits you to roughly 8 reviews over the next 6 months. While you're trying to drain a queue, adding new items is filling the tub while you empty it. The calculator above lets you toggle "lessons on" so you can see the difference - usually 30-50% longer recovery for an already-large backlog.
Standard community advice: 0 lessons until your Apprentice count is below 60 and your peak-day forecast is shrinking. Then phase lessons back in at 5/day for a week, then up to your normal cap if things stay green.
When to reset instead
If your queue is over 1,500 and your projected accuracy is below 70%, the math gets ugly. Even at 100 reviews/day, you're looking at a month of grinding with declining mental return. At that point, resetting to a level you remember well and rebuilding is often cheaper. We have a full reset decision guide on when this is the right call.
