|
|
|
* Progressions are used in order to move teams from one group to another. This can be used to progress the winning teams to semi-finals and finals round, but you can also progress teams between groups in different categories and even tournaments if you ever needed to. |
|
11
|
|
|
* Progressions use a similar syntax to php's array_slice() function or it can use defined filters. |
