Unreal Number of Reviews

Hi All,
I am have an issue with the total number of reviews being counted in my Anki decks… I certainly have not completed this many reviews… what have I done wrong to make this occur?

Thanks in advance!

Hi Florig,

I see you’re having an issue with what appears to be an unusually high number of reviews shown in your Anki statistics. This does look quite unusual!

Since this seems to be a general Anki question rather than specifically an AnkiHub issue, let me offer some suggestions:

  1. What you’re seeing may be counting reviews, not cards
    In Anki statistics, the review count represents individual review sessions, not unique cards. So if you review a single card multiple times as it goes through the learning process, each of those counts as a separate review.

  2. Possible causes for inflated numbers:

    • Importing the same deck multiple times
    • A sync issue that duplicated data
    • A software glitch in the statistics calculation
  3. Troubleshooting steps:

    • Check if the issue persists after restarting Anki
    • Try running Tools → Check Database
    • Look at your review history in smaller time periods (day/week) to see when this spike occurred

For more detailed help with this Anki-specific issue, I’d recommend asking on the Anki Support Forum where you might find users who have experienced similar issues.

Would you mind sharing what version of Anki you’re using, and whether this issue appeared suddenly or gradually over time?

This issue has just occurred today and I do not see the issue occurring any other time in my review history….

Hi Florig,

Thanks for the additional information. It’s interesting that this issue just appeared today and doesn’t show up elsewhere in your review history. Let me help you understand what might be happening with those Anki statistics.

Looking at your screenshot, the number of reviews shown is indeed unusually high. This could be due to several reasons specific to how Anki calculates and displays statistics:

  1. Time period setting: Check what time period is selected at the bottom of your statistics window. By default, Anki 2.1.28+ shows statistics for the last 12 months, but you can change this to “all history” or “deck life” scope, which might affect the numbers shown.

  2. Possible data glitch: Sometimes Anki’s internal database can have temporary inconsistencies that affect statistics calculations.

  3. Calendar view vs. actual reviews: The calendar view specifically might be showing incorrect data while other statistics remain accurate.

Here are some troubleshooting steps you can try:

  • Restart Anki completely and check if the statistics return to normal
  • Run Tools → Check Database to fix potential database inconsistencies
  • Try viewing statistics with different time frames (1 month, 3 months) to see if the issue persists
  • Check if your review log (visible in the stats screen) matches what you believe you’ve actually done

If the problem persists after these steps, it might be worth asking in the Anki Support Forum as this appears to be an Anki-specific statistics issue rather than related to AnkiHub functionality.

Would you be willing to share what your actual review count should be approximately, so we can better understand the magnitude of the discrepancy?

Hello,

I have also experienced this sometimes. I don’t know exactly what causes this, but rescheduling actions or rare bugs are the main reasons.
You said it was a one-time thing, and it’s probably not a recurring issue. This will not cause many problems with your studies.

If this really bothers you, the only way I know to revert this is to restore from a backup. You have to pick a time/day before this happened. Your collection will be restored to that time, so anything between that backup and now will be nonexistent. So you will have to do your reviews again.

But as I see in your Anki, the review count differs from the heatmap add-on. So maybe it’s just an add-on bug.

Let me know if you need help with anything else. :blush:
