consider the analogy
Steem is being created all the time at a certain rate.
It flows into your vote power barrel
...much like rain flows into a rain barrel

you can monitor the volume of your vote barrel by using SteemNow
.
Some things to consider.
100% means FULL
but just because your rain barrel is full doesn't mean it stops raining.
same with Steem
the steem just a keep on comin.
and when it reaches full
it overflows and is wasted.
.

.
in order to not be stupid
.

VOTE

.
consider a vote to be a squirt of water coming out
of the water faucet.
the more you open the faucet the more water pressure you have.
the same with steem
the higher you set your vote slider
.

the faster you deplete your votes.
.
If I understand it correctly you can deplete your vote power down to 80%
.
...and it will refill in 24 hrs.
.
So do that.
Vote in any combination you want
...a few strong votes..
or a bunch of lower pressure ones..
.
but vote.
cause if you don't, and it gets to 100%
...it overflows..
.
and it's wasted.
.
Don't let that happen.
