The basic rules of this competiton system
1st A competition it may consist of two or more periods,
2nd The competition can consist of two or more classes,
3rd A class can also consist of one or more groups,
4th Those in groups play with each other within a section,
5th According to the end result of the section the better ones slide up into an inter-class class and the worse slide lower into an inter-class class. So the better ones will be with the worse ones in the class one higher up in an inter-class class.
This is better than the traditional league system, because here everyone is ascending or eliminated ("up or down slip" in this competition system) therefore, there are few matches where one or both play without an aim.
6th In the case of several groups, the sliding down and up can be by classifiers too, ie those who have finished in the same place, they play with each other.
7th There may be more groups in the inter-class classes due to the larger number of competitors.
8th The best of the first division of the competition will only play with this reduced group of themselves in the next period,
and also the worst in the last division of the competition will only play with this reduced group of themselves in the next period.
9.A The best in the top class and the worst in the lowest class (i.e. those who cannot move up or down) they take their existing points and results over to the next period,
and everyone starts the next period from zero in the inter-class classes.
9.B The players get points in the inter-class classes based on the rankings achieved in the previous class, so they don’t start from zero.
10th If there were several groups in the first and/or last class, the groups may be merged in the next period due to reduction in the number of competitors.
