promotion/relegation

Promotion and relegation are systems used in sports leagues, especially soccer, to rank teams based on their performance. The best-performing teams in a lower division are "promoted" to a higher division, while the worst-performing teams in a higher division are "relegated" to a lower one. This process ensures competitive balance, motivating teams to perform well to advance and avoid dropping to a less prestigious league. It maintains a dynamic league structure, with movement driven by results, rather than fixed memberships, fostering a competitive environment across multiple levels.
