7 cents solo, but a small trail following me shoud bring it up to about 10 cents shortly.
As far as using STEEM POWER goes, it'll earn you curation rewards when you upvote with it, but, unless you power down and cash it out, I'm not sure how else you'd earn anything from it. If it pays out in interest, I'm unaware.
Thank you for your replies! Well, this baffles me, because I recently had a post with some huge spikes in payout, like $5+ from one upvote, and I calculated the average per vote and it was above 4 cents, so I really don't get it. What the hell voted on my post, the Loch Ness monster or the Megalodon?!
You got hit hard with whales. Millions of STEEM POWER!
I have discovered that Steem Power grows by itself, although I don't know at what rate. This is most easily seen on this account which has a huge amount of SP, which I believe belongs to one of the founders:

If you refresh the page, you will notice that his Steem power increases with each refresh, without him collecting his rewards.
Hmmm....
My calculations show an interest rate of around 1.95% per year, based on a 10 minute period of gains of this account.
Maybe this will help shed some light into the matter: https://steemit.com/steemit/@trafalgar/a-problem-in-the-economics-of-steemit
But using it to vote doesn't reduce that, I believe.
