Grade school teams who may score 4 or 5 points for a whole game may have been short changed on the knowledge aspect of the game.  Knowledge can be learned as young as 4 years old.  Children who learn through parents, the YMCA or other programs have a distinct advantage over those who begin to pick up the game at age 11 or so.  Basketball is a particular body of knowledge.  Knowing in combination with doing is generally more successful that either knowing by itself or doing by itself.  A body of knowledge is necessary to have success in a sport.
Lets start with accuracy in shooting a basketball.  Shooting can be learned and enjoyed on plastic hoops inside the house or on the driveway, lawn, yard etc.  At some point, the 10’ high rim comes into play.  Enjoying shooting the ball can be fun in and of itself as it is consistent with the purpose of the game.  Each basket is a success point of playing.
Shooting the basketball begins with the knowledge that the ball does not go through the steel of the rim to swish it.  Steel is stronger than rubber or leather, and it does not melt into a substance which allows for swishing the ball through the net.  Instead, the ball goes through the invisible air above the rim. 
The most specific invisible swish point, often termed the invisible diamond, has 3 dimensions to it.  Due to the invisibility of these diamonds, Above The Rim is designed to overcome invisibility, initially, to begin shooting.  Shoot the ball in the invisible air over the white globes and a swish occurs.  There is joy in the swish.  The purpose of the game is fulfilled with a swish.  Above The Rim trains the eyes where to focus.  Due to eye/hand/muscle coordination, shooting accuracy develops with practice that is repeated as often as it takes.
Above The Rim specifically points out 4 invisible diamonds.  There are several more as the invisible diamonds are established in a straight line to the diameter of the rim from wherever a shooter may be standing on the court. It is about 2” inside the rim and with enough arc on the ball to be in the air above the rim.  The eye is trained to pick out a particular globe when beginning and shoot over it.  Once accuracy is happening, a change of location on the floor is taken and shooting begins over another stem or in the invisible air between the stems and globes.  With practice it is very likely that accuracy will be approached at making almost every shot for consecutive minutes in a row.  Once accuracy is developed in the small world 1’ to 5’ from the hoop, the player moves back to 8’ to 10’ from the basket and back into the 3 point arc eventually as time allows.  Strength of the shooter has a bearing also.  It is wise to shoot within the limits of one’s strength.
Once again, where the eye looks, the hand and muscles can learn to put the ball in the swish points.  As a general help, shooting form may center on the shooting arm elbow be tight to the ribs on the same side.  The shooting hand is behind the ball.  Knees are bent slightly.  The body shoots the ball where the eye is looking.
