Skill level standard
Every organizer used to name levels their own way, so "Beginner" at one event could mean "Intermediate" at another. Racketa uses one set of levels for every open play, club and tournament. Players set their level once, and each category means the same thing wherever they play.
Each level, except the highest, splits into Low and High halves based on match results, so organizers can run tighter categories with the same names.
