The original intention of the badges was to use them as milestones, rather than roman numerals. If you think the wait from 1 to 25 is long, it will get even longer between 100 and 200. I'm also hesitant to change the badge system lest I provoke the ghost of Hilditch. However, if folks really want it, I can be persuaded...
Evan, it took me awhile to figure out how everyone is doing it. You are right it is not roman numbers but rather milestones that can be X-times. So I am now one night times ten. And you are somewhere over 200 but not at the next milestone.
