The "point system" is a determining factor in sports like tennis and combat sports. In tennis, matches are scored based on a sequence of points, games, and sets, impacting the overall outcome. Combat sports, such as boxing or mixed martial arts, also utilize point systems to judge performances, often leading to decisions when matches go the distance. The point systems establish clarity in determining winners, allowing for a fair assessment of skills and strategies used throughout competitions, ultimately influencing an athlete's ranking or standings.
