Life In 19x19

Hi,

I don't understand the Demotion-Zones between Gamma and Epsilon:

Gamma..First Demotion-Place (Red)
I......7
II.....7
III....7
IV.....10
V......7
VI.....7
VII....8



I don't find any word about this in the rules. Are the colors in the moment meanigless?

Basically, bottom 6 players who have played 4 games or more demote. This can be up to, but not exceeding 7th place, as only 6th place and above are secure from demoting.

So, if everyone has played 4+ games in their class, demotion will be 9th to 14th. If only the top 12 have, it will be 7th to 12th.
