That is a good comment! I honestly don't know. I found this today and had to share it.

That's what I'm guessing because it showed my vote worth at about half of what it is really worth when my voting power is up to 100%. My voting power at the time was just over 50% at the time.

I believe you are right @michaeldavid!

Mine is up and down like a YoYo. But I'll get on with trying to figure it out.

It regains power after awhile, which could explain the diversity.

Yeah, it's been a bit low for a while so I'm just going to let it build up some more.

How (or why) does the voting power changes?

It depends on how much steem power you have and the number of votes that you do per day. The closer together your votes are in time the faster your voting power falls. Like if you vote 10 times in 5 minutes then your last votes will have much less power. You can vote as much as you like though and they still count but just not so much.
