Operator notes
Several missed days usually feel worse emotionally than they look mathematically. The problem is not just the queue size but the dread of the return session.
Trying to clear the whole return-day shock at once is likely to feel punitive. Spread the catch-up across multiple study days instead.
With a balanced profile, missed days stay much safer when new-card intake remains modest. If this pattern happens often, lower new cards before changing anything else.
How to interpret this tool
Missed days are dangerous less because of the raw number and more because of the return shock. The first session back often feels disproportionately large, which is why small breaks can quietly break momentum.
This calculator shows the size of that shock and how much extra catch-up time you would need if you do not want one missed week to poison the next reading session.

FAQ
Does missing a few days mean my deck is broken?
Not necessarily. The bigger question is whether the return session still feels approachable or starts triggering avoidance.
Should I clear the whole queue on the first day back?
Usually no. If the return-day spike is large, spreading it out over several study days is more sustainable and less likely to cause another miss.
Why include extra minutes per day in this tool?
Because recovery only matters if it maps to a concrete routine. A queue is cleared by repeated extra capacity, not by good intentions.
