The problem is not with you paying 5SBD it is with that we can only vote 3% and 4% and 3% is not enough and 4% is too much. So we have to somewhat guess what the appropriate percentage is.

We don't know the actual percentages till we vote, that is the problem. So we can't really show what it will become, as that is all approximated. If voting power goes under I think 53% or so, all our votes randomly halve in value. And there is no way to detect that. And there are many such cases that we have to anticipate. We are working hard to do it but it will never be perfect. Also remember that steemit.com changes with steem price and if you look at it a few minutes later, the value already drifted.
