Is it higher than EDP national league division 1
It's its own separate group just for DA teams. Not really comparable and really its clubs B teams.
Very bad idea to equate a league letter with who is better. Some National League/NPL teams are very competitive - even if its on just a one off basis. For example - PSA team scrimmaged with PDA and was probably stronger. Similarly, we could have talked about some SUSA
teams last year, or SSS teams this year. They would outplay their competition on any stage, but those would be individual teams, at full strength.
