I can just claim that those posts were over-rewarded.
I agree, and that's not a nice attitude.
It would be difficult, though, because people can change their upvote values after you place a downvote, and that would change the percentage. (That could also be a way to manipulate the system -- place a large upvote via an alt account, then place a '10%' downvote, then remove the original upvote).
true, there's also this point that I hadn't thought of
One possible alternative would be a numerical value that is a function of the author's median prior rewards.
great idea, a median is a great way to find a common value
To make that alternative feasible, the front-end would need to display each author's median prior reward value.
another great idea, I believe it brought great points to the debate, which would make me vote positive to amend the initial proposal
I believe @leprechaun can make these changes
