How do i stablize my strength in basketball?

Don't focus on the range/strength. You have to focus on making the ball trajectory straight, and the range comes naturally. Your eyes should just figure out the distance on it's own and your body will move accordingly. Your brain is very powerful! If all else fails a simple rule to adjust on the fly is early release = ball goes farther and later release = shorter the range.

I can see where your going with this. I have been playing basketball since i was 3 years old. The most i can do is tell you to make sure you are shooting the ball with a good form and practice. When you are shooting, don't immediately start shooting from far away. Do some short range shots, layups and get into the groove. After shooting some close range shots start geetting farther and geetting used to the range from where your shooting. best of luck
