Kanji by Grade

[Knocks]

I use Rikaichan obsessively and have noticed that it uses non-standard level designations for kanji. For example, it has kanji levels numbered 8, 9, and even 10!

I thought that kanji grade levels basically meant the corresponding grade in Japanese schools where those kanji are learned. My DS kanji program (Kageyama Method) divides the 1945 jouyou kanji as follows:

１年生　　８０
２年生　　１６０
３年生　　２００
４年生　　２００
５年生　　１８５
６年生　　１８１
中学生　　３１６
中学上級　２８６
高校生　　３３７

Could somebody provide the number of kanji that Rikaichan thinks are levels 7-10? I suspect that 7-8 are the rest of jouyou, 9 is jinmei and possibly other everyday kanji that are not in jouyou, and 10 is something even more rare.
