With this figure you will have to hit for ~3.92 weeks to reach 50k. So it will only take around 4 weeks to accomplish hitting 50,000 balls if you were to use my weekly hitting schedule.
Working on the backboard, I think you would get 2x or even 3x that if you were focused.
Well, as long as you didn't hit the ball over the fence and have to spend a lot of time trying to find it.
