Oh and I forgot to mention!
Those figures are accurate only if everyone voting is at 100% voting power, and that is rarely the case. I myself am usually below 50% voting power.
Also, since most people have very little SP, their ability to vote is dependent on whether or not their vests even allow them enough broadband to vote. Given that the vast majority of my followers have the same about SP as 95% of Steemit population, they often can't even vote for me because their vests are so low that they easily go beyond their broadband allocation.
Horrible, but true...
I myself was stuck in that hole for a long time.
But don't let the low vote value discourage you; the goal is to make quality content for the sake of making quality content.
