To answer this question needs more than speculation. There is a reason why I have got a peg on my nose and I am deploying the fastest single node I know of to build behemoth database query engine for doing precisely the analysis that will give us a nice little graph showing exactly how much the majority, versus the outliers, plus exactly who that is...

You no better answer the question than I do, by your own standard.

I am uncertain why this analytical work has not been done, considering the amount of words that none other than @dan has spent discussing the topic, in relation to reward calculation formulae, and the question of how to ensure that the distribution approaches this equality, while accounting for community consensus about what is quality and what is not, since obviously the whole purpose of having a forum is null and void if you just pay out 9.3%, or whatever the momentary rate is per unit of time.
