N-Police, let me cut to the chase because I have to get down to the hot-tub and the pool to prepare for my 11:30 rec/practice match. The only way you'll find out where you stand in the competitive tennis world is entering Senior Age Group tournaments where you are competing on a level playing field with gents who have been suffering the pressures of gravity on the planet for about the same amount of time as you have. All this NTRP number stuff is hot stove league, Monday morning quarterbacking and some heartless and soulless computer AlGorerhytm making judgments about you. Play in your age group and you will immediately and objectively discover what your tennis mettle is made of and play with players who know the rules and rarely cheat.
