It cannot be taken advantage of.
If you vote 1% at 10 minutes, you are near the front of the line. 2 days later you decide you want to give it 25% instead, you are charged 15% voting power to raise your vote to 25% and you are now at the end of the line.
In fact, it would close a loophole being actively manipulated right now.
You mean charged 24% right? The delta
Sorry yes I was used to using 10% and 25% as my example.
