First of all, I think you don't know the fine rules of discourse too well, because that's not how you discuss.
Second, I am quite decent with math and code.
If someone can with a specific quantity of VP "bid" on the value of a post to guarantee it. And in the end, let's say the post is highly over or undervalued all this VP will be used, no adjustments needed. If the value of the post is exactly what he voted for, at the end of the 7th day, the chain calculates this, and refunds him the unused VP. End of story.
