Who really care what someone's NTRP rating is? It has no bearing on tennis, how good you are, or what you want to do. The only time it matters is when you are trying to play in a rated league or tournament, and even then, most everyone is lying about their rating.
Just focus on your tennis and get as good as you can. Don't worry about distractions like this (NTRP).
