Yes, four tickets per qualifier per team. That has not changed.
What has changed makes the answer to your second point no, because as of today all state tournaments will be ran on 4 mats. When asked my opinion on expanding to four mats my response was the number of coaching bands being given. As a result, the state will grant the number of coaching bands based on the number of qualifiers as they normally do every year. So, that will not be a problem, or at least it shouldn't be.
In 3A, we will use four mats for the first round and the quarterfinal round. After that we will go to two mats for the semifinal round then wrestle consolation finals on two mats. The finals will take place on one mat.
That being said, the state finals for 3A are scheduled to begin at 5pm. I'm sure the others will all begin around the same time.
