How basho points are calculated 

For every win you get 100 points + bonus points dependent on the rank of your picked Rikishi (see table below). 

Bonus points: 
1  1st Makuuchi Rikishi (mostly Yokozuna East) 
2  2nd Makuuchi Rikishi 
:  
42  last Makuuchi Rikishi 
43  Juryo 1 East 
44  Juryo 1 West 
:  
70  Juryo 14 West 
71  any Makushita Rikishi 

For example: If you pick the Rikishi ranked at Juryo 1 West and your picked Rikishi wins his Bout,
then you get 144 (100 + 44) points.
If your picked Rikishi loses, you get 0 points. 
The basho points are the sum of all achieved daily points. 

How ranking points are calculated 

Ranking points (RP) are calculated by this formula:


RP =
1.0 * BP1 +
0.9 * BP2 +
0.8 * BP3 +
0.7 * BP4 +
0.6 * BP5 +
0.5 * BP6 

where BP1...BP6 are the basho points
of the last 6 Bashos you had no Kosho* status. 

Missing a Basho / Kosho* rules 

For the first missed Basho
you get the Kosho* status automatically.
If you miss two or more Bashos in a row,
you get the Kosho* status only for the first missed Basho.
If you are absent for three consecutive Bashos,
you will be removed from the ranking list.
