Hi dear Fabrizo,
No, it is not right. In classical fighting of King Fu To'a, we have one to one in Anattawa stage. Again in Atado and Suto we have one to one fighting which one person does Atado and the other Suto, but when they pass it, they would gain two levels at the same time. Next which is Samsamaeh and Mayana, one person does Samsamaeh and two people who are against him do the Marana techniques. After that it is one to four, in the middle one goes with Waiyma Mato and the other four attack with Kuana techniques. The last part is one to six, Westa Mayana and all other techniques.
Don't forget they are some classical rules in all sections and parts. I will explain them in Paris.
Have fun and good luck.
