Technicalities:
I will rephrase to the below
The model you chose to showcase and is displayed in your OP and also seem to lend support to.
(3) That might be true but the vocal point of the model is value taken from the blockchain (traded Hive). My counterpoint is traded Hive that goes towards apps or a business on HIVE is not value extracted but value shifted within the Blockchain. This should be encourage as it promotes the blockchains self sustainability/ helps grow the blockchains apps which in turn grows the chain as a whole which benefits everyone.
My point is, most of the “extractors” doesn’t have any SL assets either. They have sold them too.
That data can be collated but will take time. I have manually spot checked many accounts.
One example

No where in your OP does it state anything about held Splinterland assets being part of your equation. You are free to bring that point up now and you just did but I can't factor it into my response before the point is made. I would agree that such people could fall under the extractors definition dependent on where that traded away value went. I haven't checked the account you shared above but I'll take your word for it. But just as you found someone who might highlight the displayed system in your OP works there are others that (as I see it) get unfairly categorized (A) those who shift value on the chain vs. (B) those who remove value from the chain. I know you are likely a busy person so thank you for taking the time to respond. There isn't much else I can add here so I will have to bow out of the conversation.
The equation in your OP:
If I divide Author Rewards + Curation Rewards by Held HP, people who held more HP than they earn will have a fraction less than 1.0. Those who held less HP will have a fraction higher than 1.0. This is the Krampus Co-efficient! Or KE. KE = (Author Rewards + Curation Rewards)/Held HP KE = 1.0, you hold exactly as you earn (approximately!) KE > 1.0, you hold less than you earn KE < 1.0, you hold more than you earnThe description and explanation that is described in the post is accurate.
And yes, personally as a hive stakeholder I may or may not care how much Splinterlands assets any individuals holds.
