In Wisconsin, regionals are the week after UCA nationals & state is the week after. The judging is WACPC (Wisconsin Association of Cheer & Pom Coaches) Style. And the divisions are different. Small is 0-11, medium is 12-19 and large is 20-36. They judge you more on cleanliness, less on difficulty. That being said, yes a team with solid extensions could beat a team with libs that are solid, but maybe a bit shakey. For state they take the top three teams in each division from each of the regionals (southern & northern). If there are only two teams in your division at your regional then lucky you! You both get to go! This past year my team competed small varsity at all events, and they all scored the UCA way and we placed really good, but at regionals we had to compete as medium. We had 14 girls on our team because we put in our 2 alternates(BAD CHOICE, IMO) because we could do so and stay in same division. Personally, I think that was a horrible idea. Should have kicked one off for the competition so we could have competed small. We got 4th :( After looking at the scores from every other division we would have placed top 3 in every other division except D1 medium...and if we could have competed D1 Small we would have won...smh.
Sorry for my rant, still bitter about regionals. It was NOT a good way to end my high school cheerleading career. Hope that could teach you a little about how WI runs state.
