Only FIBA tournaments for full five-a-side teams are used in calculations for the tournaments. Other tournaments, such as regional championships, invitationals, and friendlies are not included. Also not counted are tournaments in FIBA's official competition for three-on-three halfcourt basketball, 3x3.
As opposed to football (soccer) tournaments, teams still have to go through a series of consolation and classification rounds even if they've been eliminated from title contention, so that a complete ranking of the teams will be possible.
The calculations are done after the tournaments stated above in a group of two Olympic cycles (8 years). The oldest tournament outside the 8-year period is discarded and replaced with the newest competition.
