The actual brackets formats are not made public until after districts so that people do not intentionally lose to position themselves on the state bracket.
All that is known for certain is District 1 will wrestle District 2 in the first round and District 3 will wrestle District 4. The first round will matchup 1st place wrestlers from district vs 4th place wrestlers and 3rd place wrestlers vs 2nd place.
You can also be certain that the 1st and 2nd place from each district will be on opposite sides of the state bracket so that if the two best wrestlers at a particular weight are from the same district, they will not wrestle until the finals.
