Using steemnow.com, I was able to watch someone upvote all the time at 100%, but with a low voting power in the 20% range, and still give 15 cents for a comment, every time, and they had less SP than me. And here I was, using a 10% voting percentage to save my voting power, but I was only giving rewards of 4 cents -- how very big of me, lol -- not! That's when I began to question the goal of keeping a high voting power. There are a lot of good content creators!
