Hi
Here is what I could learn from the other picture. I'm not a translator, I checked with 2 translations extracted from the picture.
The "Circle of Attributes" is the level of mastery for each category of the Hatsu system.
Superior Level
Excellent Level
Natural Talent Level
Extreme Level
This is an overall "in the moment" evaluation based on learning speed, physical ability and mental strength, and is not an expression of the strength of the special ability.
As you work, you move up in the rankings. There are cases where one does not move up even if one is in the "Circle of Attributes". A person with a ranking of "Natural Talent" will only fall to the rank of "Excellent" or "Superior" due to insufficient training.
A person whose abilities are halfway between the two categories can enter the "Circle of Attributes" if he continues to train only in his natural category over a long period of time.
(Not sure about the translation of this one)
A condition for awakening to the "Extreme" level is to work in all categories. Note: This is apparently what Biscuit said during Greed Island.
The term "Extreme" refers to the fact that the ability has reached the highest possible level of competence, and does not refer to the value of innate talent. It depends not only on the efforts of the individual, but also on other factors such as luck and fate.
Gon was placed in an intense state of mind and reached the "Extreme" level instantly, but lost his special ability due to his oath.
To be confirmed, but they seem to say that Gon lost his Jajanken, since they are talking about special ability.
