I think you're looking at the draw order, not the eligible bands. You have to go to http://www.txbands.com/forums/index.php?/topic/6437-2014-uil-region-results/ to see the results from the Regions. As of this afternoon, Area F looks like this:
F - Region 9, Region 10(1), Region 17(11), Region 19(10)
The numbers in parentheses are the number of schools from each region who received 1s at Region.
So far there are 22 schools eligible for Area - add up all the parentheses. If no schools from Region 9 qualified, only four schools would go to state from this Area (22 / 5 = 4 with some remainder, = 4 schools). If I read the Region 9 website correctly, there are only 12 bands competing on Tuesday for their Regional. If all 12 bands from Region 9 made 1s and chose to compete at Area, that would only leave six schools from this Area (34 / 5 = 6 with some remainder, = 6 schools).
As someone rooting for Clear Lake, the math is deeply disappointing. The addition of Friendswood and Dawson was a double-whammy.
UPDATE: obviously I also missed the subtlety the two band minimum. I'm a lot more optimistic about Clear Lake squeezing into 7th than 6th. Bring on Saturday!
