Your voting power decreases 2% for every 100% upvote (100% is the only option for minnows until you reach 500SP and get the slider so you can adjust your vote%). It takes 2.4 hours to get that 2% back. So you can vote as much as you like, however the best number if you want to keep your power up is 10 votes per day because after 24 hours your voting power will have grown back 20%.
But you can vote as often as you want and not worry about voting power. It really isn't that important for minnows because minnows can't get curation rewards for voting.
I'm also confused :P
