Its clearly not per Vote Count (though you probably will notice this by the time I finish this post, indicating you weren't ENTIRELY kept up), as you'll note Rat voted, made the comment of "I did 17% with my vote!" and when he removed it, Soppy was still at 10%.
Umm...if you're lost by this logic?
Sopko First Vote Count: 5%
Sopko Second Vote Count: 22% (Rat Voted him by this point)
Sopko Third Vote Count: 10% (Rat Unvoted him)
Simple math will show what I mean! My guess is its either # of Votes, # of Posts, or time interval. Its clearly something that gets gradually higher as the game goes on in some manner.
Also, I don't trust the Blue Haired Swordsman!
...wait, there's two. Ok, I don't trust the MANLIER one. Why? I've yet to see a trademark yell of his favorite attack! Also, he's talking about SCIENCE! I smell an impostor...well, no, I don't, but I'm sure Ivysaur does, so...
