bug in statistics

Sometimes I open the statistics panel in Anki to see how many cards I have and the numbers don't add up. For example, in the attached screenshot it shows I have 513 cards. I add on average 34.2 cards/day. It means 342 cards in 10 days. 684 cards in 20 days. So, in the last 20 days I added more cards than the total I have? It doesn't add up.

I'm using Anki 2.1.26, no plugins.

    The graph shows a span of ~ 28 weeks, so I don't understand your report.

    That's exactly the point.

    The graph shows ~28 weeks, that is ~196 days. It shows a total of 513 cards. 513/196 = 2.617 cards/day.

    But the report says 34.2 cards/day. 34.2 cards/day * 196 days = 6703 cards in total.

    The average number of added cards is not correct.

    Thanks, you're right - it's using the age of the currently selected deck instead of the entire collection. Fix will be in the next update.
