Does the distribution chart include the 'steemit' account? That isn't a real account at all in the sense that it doesn't post, doesn't vote, and isn't an actual person. It is part of the bootstrapping capital structure and distribution model of Steemit/Steem. Those coins are effectively 'undistributed', much like the portion of Bitcoin's supply that hasn't been mined yet. It really has nothing to do with aquatic life.
EDIT: the steemit account is excluded
I dont think it does. the top 40 accounts look to be averaging about 2500 MV each so that totals 100,000 and steemit is ~250K, so with the rest of the aqualife adding to about 40%, that would mean all the <1000MV accounts total either ~60K MV or nearly 200K MV
I confirmed the steemit account is excluded.
