I currently have 685 karma at 65% positive. Assuming 200 downvotes from Eugine, upvotes of X, and legitimate downvotes of Y, then X/(X+Y+200) = 65% and X-Y-200=685. Solving gives Y=599, X=1484. So without Eugine I would have had 885 karma at 71% positive.
If I had 300 downvotes from Eugine, that would be Y=511, X=1496 which is 985 karma at 75% positive.
