It is most likely that we never will hit a full 960k in one day, because everyone will size down there coin blocks so that they won't hit the 1k limit....
What does this mean?
Should I resize my blocks BEFORE they hit 1000?
It means that you want to have small enough coin blocks that they have a reasonable amount of time to accumulate stake reward before they will hit the limit. Try using the built in stake calculator. A coin block of 1,600 HYP can go for 30 days without hitting 1k reward. A coin block of 2,500 HYP will hit the max if it doesn't stake within 20 days.
So you decide whats best for you. It is a play between "how fast do I want to stake" and "how much do I want to avoid the max reward".
