I was simplifying it for the sake of simplification in the comment, I'm well aware that the value varies based on many things (VP, reward pool, curation, SP, etc).
But, for sake of simplifying the implementation, all this "could" stay the same, the only thing changing would be anchoring the value around a certain value the person assigned to the post.
The algorithms that compute the value of your vote on a post do not generalize that value. They set it precisely. Since the target value you assign a post is attained, or not attained, depending on all the votes cast on a post, the calculations become impossible as the VP of voters is depleted or recharged by voting.
Multiple variables that are calculated exponentially increase the complexity of the calculations to account for each other, and this level of complexity is unattainable with our present tools.
But the same problem exists at the moment too.
No. Your proposal adds a layer of exponential increase in calculation difficulty. The decay of VP is calculable since there's only one factor to calculate. By introducing the target payout of the post, you multiply that calculation by all the VP applied to the post. This is incalculable.
The user still applies a certain VP to the post. If less is used he gets it back after 7 days, end of complexity.
You appear not to math well. There is no way to ascertain the result you seek.
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.
Provide examples. The calculations requisite to determining the VP expended on a post are two-fold in the situation you describe. The first aspect is the VP expended by the voter, which varies depending on the votes expended. The second is the VP of all voters on the post, which determines it's payout. Given that all voters' VP is variable because all voters are voting on more than that one post, this requires that all of their VP be accounted for when payout is calculated, and then the weight of the votes cast that are based on that payout to be adjusted to approach that payout as possible.
This is two variables that depend on each other to be calculated, which isn't possible to do.
Suppose you were target shooting on a world with randomly varying gravity. Where you aim the bullet is determined by you, a variable that cannot be precisely predicted, just as the gravity pulling on the bullet cannot be predicted.
There is no calculation that could be made to accurately aim in that condition, because the two variables depend each the other on the calculation of each the other. It is an insoluble math problem.
Show me the calculation of VP and payout that could deliver payouts. No such mathematical solution exists. Pointing this out isn't rude. Claiming reality is rude is unreasonable.
