I had to read this article 3 times - and I'm a mathematician - to see the key sentence! That however many daily votes you do, you will end up at some average level of voting effectiveness commensurate with your number of votes. At 40 votes per day, your account bounces around between about 15% and 35%, averaging out, as @timcliff says, at about 25%.
One comment mentioned the psychology concern of "losing power". There is a good case there for possibly doing something within the UI to change that perception. On chainBB it tells you to a fair degree of accuracy how many more votes a user can make in order to stay at your current level. I find that useful.
Thanks for the post - useful change of perspective.
