Maybe the point is that 5A and 6A brackets at regionals are 8 man brackets, while 4A and 321A brackets are 16 man brackets. All tournaments qualify the top 4. Although many smaller school brackets are not the full 16, neither are the 8 man brackets full. It stands to reason that wrestlers who would not qualify at a 4A regional could get through at a 5 or 6A regional. If you would like to argue this point you are certainly welcome to, but it would be a baseless argument.
