I've been tracking my progress toward the silver calculus tag badge. The other day I noticed that the score hadn't changed for a while. Since I answer calculus questions all the time, I knew something was up. I checked the "tags" section of my account page, and saw that indeed my score had increased, but that this fact was not reflected in the progress report. I quickly switched to tracking progress toward a different badge, and then back, and the score updated. But again, it has not updated since. Here is a screenshot:
I've searched meta, but I haven't seen anything like this. I can understand a lag between an event and updating this report, but it seems to me that the lag is pretty long, at least a few days. I am wondering, is this a bug, or is there a reason for this?
After checking a few other users' profiles, I see that this effects, it seems, everyone.
