So the minimum at you account for the whole year does not exist anymore, is that what you are saying? They will not ask you about what you have in the bank when you do a 90 report, thats only when you apply for a new 1 year visa.
But....the amount can never be less than 400.000 and all 800.000 has to be on the account for a couple of months before you apply, so it's a little bit more complicated. Unless they only care about if they can only stay for 1 year and then leaves.
