I have no idea what that means, but if we consider our true income to be only the part we get after the 7 days of voting, it'll get simpler. The default income is always 0, and whether we hit above that after the week is over, that is what we can really call income.
The "Potential" in front of the figure means it is not yet income, and even then we have to pay half of it to the curators, and in my case I have to pay 3% more to eSteem, unless I want to use some other front end. Steempress takes 15% which is kind of harsh.
But after all these are taken into account, whatever is left is our income. (Albeit we might still need to deduct exchange fees and taxes from that, so our net income is way smaller than that.)
Yeah, maybe it's time to stop whining and just ignore the troll.
