Andre Agassi's father's philosophy was that if he made Andre hit a million shots a year, then he would be unstoppable. I did some rough math (it was hard to guess how many balls I hit at a lesson or in a match) and discovered it would take me about 19 years to reach a million balls at my current playing rate which is 1 lesson and 1 match per week (2 if I'm lucky). What do you think is the best predictor of playing level? Time playing in years, Time spent playing per week or amount of balls hit? Obviously they will overlap, but say someone has been playing 2 years and has hit 100,000 balls, and another guy has been playing 6 months and has hit 200,000 balls, who would your money be on? How many balls would you guess you have hit and what is your playing level? Any ideas on how I can get more playing time? I really can't afford to hit with the ball machine more than once a week and I have virtually no one to hit with.
