I still have some work to do before reaching the PostgreSQL gold badge, so I chose it as the one for tracking. Unfortunately, it seems to be stuck. See the screenshot below:
I am not posting about anything else than Postgres (except comments), don't get many upvotes on answers on other topics (or question in general), so I was expecting the counter advancing nearly linearly with my reputation changes. But it does not happen:
Please note that between taking the two screenshots, two days passed - so it's not like not waiting enough for the updates to be triggered.
Meanwhile, in the top users view of the postgresql tag, I seem to have accumulated some 221 answers with a total score of 727.
