I totally agree. Yeah for the median/whales it's impossible with a constant number of posts and a constant HP.
If the number of posts decrease you could have an increase in median (as there's less posts) and a higher increase for the whales' posts. As there's the same amount of HP divided into less posts, then both are possible.
What I wanted to say is : as long as there less activity/posts on the chain, it's too soon to draw any conclusion about these numbers. We need either the same number of posts that Steem had so we can compare, or we need a few weeks of data to have a new standard for the Hive chain, and then only we can see how it evolves.

But for the part about current DPoS being incapable of decentralization, the current elite being better than the one on Steem and the need of a better system, I'm 100% with you.
