This website show five different spot and different distances. A basketball player shoot from different place with different speed. They analyze the data and calculate the average. It show the range of the place.
This helps me because you shoot from different spot and it show your average of different spot you are shooting. It’s important to get rebounds for your teammate so is more advantage for your team. It’s also important to stay focus while you are shooting and defending because you don’t want to make your team angry.
