I still don't get how giving a brewer an extra week or two to brew a beer for a second round at the very end of June offers any competitive edge, but I don't want to derail your thread any further. Your scores are good, and hopefully the judges provided good feedback for improvement.
I think the minimum score (going by my memory) to advance is 30, but I'm pretty sure that your 30.5 score will be beaten, as the 14C category is very competitive! That's a pretty darn good score and you have reason to be proud of it.
