Can someone who has actually played League/tournament tennis please provide a description of what these levels REALLY mean and not just what is on paper???? What can these players really do on the court? Maybe everyone has a different experience for what each player should or actually can do at each level. The descriptions are so vague.....it's truly silly to have such vague rating summaries listed as the USTA has done. For example, can a 2.5 consistently serve and utilize backhand, forehand, serve, volley, lob effectively? So, if you had to state a brief description for each of the most popular levels what would you say? 2.5-? 3.0-? 3.5? 4.0-? 4.5-?
