Isn't that the point of making it 6hrs? To allow for some compaction?
I've said it before, but I don't like penalizing 1"+/hr rates on the tail end of large, long duration storms. In LES land...if you pull 20" in 12hrs, clear, and then another 20" in 12hrs, but the depth only increases another 6"....does that mean you should have 40" or 26"? If both 12hr samples had the same rates with the same amount is it fair to report it as 20" for the first 12hrs and only 6" for the last 12hr?
