That metric is completely arbitrary. You could take a screenshot of one mod being the only person on chat late at night and say we have too many mods because the ratio of mods to users is 1:0. That's an unusual case, but so is the one in this screenshot. I have not heard many sound reasons why it's bad to have this many mods.
