It would be interesting to trace changes after the next hardfork with vote balancing
Rebalanced target votes per day from 40 to 5. Votes will still regenerate over a 5 day period, so an account can vote 25 times sporadically before incurring large penalties to voting power, or 5 times daily.

Currently, top influencing whales voted much more than 5 time a day (e.g. smooth did 33 times on average, and wang did 73 times!) The change will dramatically alleviate the concentration of influences.
