Is it actually possible to calculate this? I don't intend to be a critic, because I do actually think this is a really cool idea, but it seems like this is an impossible number to calculate based on how the site works.
My understanding of the payout system is that there is a set amount of Steem to be distributed (we'll call it the 'payout pool'), and the system decides how to divide up the pool based on the votes/weights across all the posts. Based on this, is there even such thing as a set 'upvote worth', since it depends on how all the other votes are distributed across the active posts?
To give an extreme example, let's assume there was $50,000 in the payout pool and nobody on the entire site voted for any content except for one user with 10 SP voting on one post. (Yes, obviously this is an extreme example.) In this case though, the one user's upvote would award all $50,000 to that one post.
I am not 100% sure that my understanding is correct here. If anyone has a better understanding of how it works - to either confirm what I am saying, or show how it is totally wrong - I would appreciate it :)
Yes, you are correct. I tested it with the votes of 10 of my friends and it seemed to be correct. But we are between 500 and 15.000 SP. Unfortunately I did some miscalculations that I will try to solve. I hope that I'm able to get it right.
