Similar to what SBI is, but using a model that allows me to use the entire buffer in one go if I wished for.

In alternative to that, for the ones not liking the model, a way to let's say, ONCE per week, be able to spend 100% of my voting power in 1 vote. And then you would need to wait 7 days for you be able to spend more than 2%. In balance to the unbalanced way to consume Voting power, you would also consume equivalent amount of your RCs. This way you would avoid schemes. Sort of like a berserk mode of voting. You have 100% of berserk power to spend per week, which would entitle someone to spend more than 2% per vote up to your available SP.

I have probably confused you by now... but I will work a better way to tell the idea, and when I am ready (or if still makes sense) ask around to see what people think of it.
