Hello sorry to bother again. This is appearing on my heatmap. 1494 If you go to the browser and put due= 1 and 2 you’ll see that the 1494 is divided between tomorrow (Saturday) and after tomorrow (sunday) and the total is 1494 its is divided like due = 1 769 and due = 725
Why is this happening ? I deleted the add-on and redownloaded it. I want them divided though !
Hello,
This add-on may rely on a different interval calculation to determine the due date. Since we are not the authors of this add-on, we can’t provide an exact explanation for that.
The Heatmap add-on received its last update in 2022, as shown on its add-on page, so it’s nearly impossible to know how it interacts with Anki’s newer interval and load-balancing mechanisms.
If you’re not experiencing any issues with your actual review due dates, there’s nothing to worry about.
Let me know if you need help with anything else!
