I admit I do not know how Nebraska does their classifications.
For the most part, I have found Nebraska and Kansas pretty close in most of their rules. In KS we were on two year cycles and the numbers were separated boys and girls from classes 9-11 from the previous year. Occasionally, you would get the odd situation where a team would have one sport on one class and another class in others because of numbers in those classes and numbers to field teams.
I cannot believe in my wildest imagination, any state association weighing facilities in a decision where teams were placed. I used to go to those meetings every year, it was very cut and dried assuming your secretary counted correctly which I heard happened one time.
