You know, bronze are 10 points, silver are 50, and gold are 100. Divide it all by ten, and bronze is one, silver is five, and gold is 10. Same ratio, still worth as much relative to other badges.

Just because they stuck an unnecessary zero at the end of everything doesn't mean it took you any longer time to get it. :/
