No worries man, the reason for the delay is such that everyone finds out at once, so no one gets an advantage if they have to re-brew a batch. (This is kind of shorted out by people getting their scoresheets early...)
Another reason is so that people enter their designated region, and everyone doesn't flood a well organized / fast reporting region. (Again, this only works if people stay quiet about their scoresheets.)
Lastly, I think it puts the fire under the rear ends of the competitions that are later in the month / trying to finish up if they know that the whole NATION is waiting instead of just one region.
That's the best reasons I can think of.
