How long do Tireless and Unsung Hero badges take to be awarded?
I've been puzzled by this one by now. Got my 11-th zero-score accepted answer more than 3 days ago. Have a total of 32 accepted answers (meaning the percentage is at 11/32 ~= 34% > 25%).
Is there something wrong with the calculations or my understanding of the requirements, or does it simply take more time to award the badge?
