Yep. 4 classes has unfortunately watered down the quality of competition at the state tournament level. Only one game today was decided by single digits. 4 team districts, and 8 team regions mean that 25% (region champion and runner up, 2/8) of teams are getting to play in sectionals. Compare that back to when there were 3 classes. 8-9 team districts, regions were between 15-18 teams.
With 4 classes we are getting matchups of the top 25% but with 3 classes only around 10% of teams made sectionals.
