If I understood exactly about what you said, It doesn't matter I guess.Ranking Criteria wrote:
A difficulty's name must indicate its level of difficulty, with the exception of the hardest level of difficulty in a set. The mapset's hardest difficulty may use an appropriate custom difficulty name, unrelated to a username. Mapsets may also use a complete set of custom difficulty names that clearly indicate their level of difficulty to the player. Marathon maps with a single difficulty may use free naming.
