A 70 rep account with less than 10k hp has dumped at least that much on the market forcing down the price for everybody else.
Uhm, I realize that although the rest of the discussion is still related to the main idea, I get the impression that somehow we have gone off on a tangent and deviated a bit from the main topic.
It all started when you say you believe, and that's how you have insinuated it, that any account in Hive that has reached a reputation of 70 should at least have accumulated and present today an HP of at least 10k.
And what I've tried to clarify and demonstrate. Is that some of us here with a 70 rep, have not managed to earn and accumulate 10k Hive in rewards, earnings and payouts. Not even if we add the HP that came to us directly as HP plus the liquid Hive & HBD that we have been earning if we had decided to Power Up all of it. And in my case, not even by working here for more than seven years and regardless of the few times that I've been forced to Power Down and withdraw some money in fiat.
In my opinion, I think I must have earned about 5.8k or 6k Hive at most throughout these seven years. 
I'm still waiting on an answer.
I have two accounts with 72 reps, ones says ~9k and the other says 6500 so we will have to get an answer to whether hivetasks shows a total or half.
I'm guessing half because I have double that amount in hp.
These are the hp's of the page I am on in hivebuzz.
Mine is the 5th one down and matches what hivetasks says.
We need an explanation as to why there is so much variation in the amounts.
Yeah bro, don't get entangled too much. You can currently have double, triple or ten times the HP indicated by both Hivetasks and Hivebuzz. But that's only because you may have purchased Hive in the market that you Powered Up or because you've rented it or had it delegated to you by someone else.
While what Hivetasks shows in the pictures I gave you and what Hivebuzz shows in its statistics, is exclusively the HP that you actually have earned from "curation rewards" through the upvotes you have given and the "author rewards" you have earned through the upvotes that others have given to your own content. Posts and comments. :)
There is no variation really. What Hivetasks and Hivebuzz indicate is only the HP you have earned during the entire time you have been in the chain, but exclusively coming from your content curation and content production. It doesn't matter how much HP you currently may have in your wallet that comes from other sources. That's all.
