I was pretty excited the day I noticed the slider bar appear. I didn't even know it was an option until it just appeared one day when I'd acquired enough SP to get it. It makes it so you can vote more than 10x per day without dropping below 80. When I was new i didn't know any better and I depleted my voting power very quickly---giving out upvotes like Oprah.

I wish it was easier to set the voting % on the esteem mobile app. It's hard to make it land on a round number with no decimal and sometimes the vote doesn't seem to take (get an error message) when set at certain values. I prefer steeming on my PC but I'm not home very often unfortunately. At least it doesn't seem like it.
