This morning I was awarded the bronze badge for the real-analysis tag. According to the description page, this badge is awarded for “at least 100 total score for at least 20 answers in the real-analysis tag”.
I reached those thresholds several weeks ago but didn't receive the badge. At the time, I didn't mention it because I didn't care.
But I believe that the threshold is actually 25 answers, not 20, and that my posting of my 25th answer with that tag, yesterday, is what triggered the award of the badge.
If this is correct, the description on the description page is inconsistent with the award, and at least one is incorrect, and should be fixed.
It's plausible that the description is correct and that nobody noticed the implementation error until now because it's much more easier to reach the 25-answer threshold before the 100-point threshold.
