I would like to add that the more steem power you have, the more you can split your upvotes.

Yup, that's true. I remember long time ago being a red fish and having no voting bar in Steemit.com. That was the biggest reason I started using busy.org at the time, they had a voting bar even for the smallest fish, not that it would make a difference or that it would wise to split your vote when you are so small. But you at least feel in control of your voting power.
