In my experience scores vary drastically in the first 20 votes, it\'s almost not worth watching when a single 5-6 can trash a score so much. Once they hit about 30 they start to level out a bit, 50 moreso, and eventually they kind of fossilize and are really just dug up by people who are deliberately looking for it
But yeah, there have been problems with sniping in the past, where some people make it their mission to trash the scores of honest painters for no good reason. Only the admins know just how often this kind of thing happens, but if you watch scores carefully in the beginning you see there\'s a ton of variation in voting that simple averages will never be able to tell you.
