Also the attack described would not work.  Coins are not staked only on coinage, it is only one factor.  So even if you made a lot of transactions so all your coins were separated by a small interval, there is no guarantee they will stake at each interval - in fact splitting them into small amounts to make these intervals will make them less likely to stake. You would have to have a very large amount of coins at each interval to even have a chance of producing 2 consecutive blocks.  This attack is completely unrealistic.
