Statistics: Most Types Voted
With every pair of (user painted badges) badge (type) images displayed in user polls and judged, a player votes on two badges.
Thus, with one vote you have voted on two types, however later it might happen, you are shown the same badge type twice, meaning the number of voted types is usually lower than twice your number of votes.
