Smooth has adjusted his votes accordingly and saying there's no methodology is not correct, not only is there the methodology of downvoting where bots/whales have upvoted therefore the rule is evident but its neither sloppy in that regard nor outside consensus, because it's also evident that it wasn't a singular effort and for consensus to happen for such an experiment is unfathomable in the real world, so the consensus happened between those that took part.
How did they game the system if they used the voting power to effectively negate any gain? The experiment allowed me with meager 300SP to influence posts not worth even $2 by one cent and post worth $17 by 10 cents, therefore it's a success in that regard.
