Be efficient (Ep 2)

Before we start experimenting, we set a model that fits the situation. It is irrefutable that in a situation where a sphere is rolling without slipping and we are ignoring the air resistance, the moment of inertia of the sphere is (2/5)*MR^2 (M is the mass of the sphere and R is the radius of the sphere). Some people have stated that shooting underhand instead of overhand is more effective for a minority of the people. I want to say that if a person fits the model of the scientific experiment which concluded that overhand is the most effective way, then it is quite stupid to argue.
I am not trying to say that "all" people have a single shooting form that is the most efficient. There may be several factors that determine a person's shooting form. Psychological and physical factors exist. For example, a person might feel more emotionally stable when they are shooting underhand, or person might have physical differences that makes him/her deviate from the standards of the model. Research concluded a single shooting form that is the most efficient because forms such as the underhand increases the chance for the guard to block the shot. Because of the increase of height difference to the basket when shooting underhand, the player has to shoot with an increased angle, which is quite difficult. Some might state that people might feel more comfortable in a different form or say that he/she have already trained for so many years so it will be difficult to change their habits. I'm not trying to say is not pressure the accustomed to change. What I'm trying to say is, "If the players trained psychologically and became the standard model which fits the results of the research, then they would have been more efficient at the sport than they were before.
It is true that people without marked individuality would make the game boring, but if the purpose of playing the game is winning, then people would have to be mechanical and be less flexible in their playing styles. It would degrade the fun in the game, but it would make the team win the game
