Variety German Euros

The topic
https://en.numista.com/catalogue/pieces105.html
introduces abbrevations KMB and "Variant 3" with some figures in brackets and gives no explanations.

Could you correct that please.

That is: the meaning of the terms and the meaning of figures in brackets.

I do not know if I'm allowed to link to another forum, but here are the mintage figures and a few pictures to the variants. Someone must have used the German abbreviation for "small coin design" KMB (kleines Münzbild). The percentages seem to be for the proportion of the entire mintage.

I'd like to know the exact meaning of the figures in brackets. There is no place for guessing - it's catalog, but fiction.

Yes, thank you for the possible explanation of abbreviation.

It seems that the small question is not solved yet.

I have to give a link to resource of information, and intend to mention numista. But the information is given in scetch, that is not appropriate for use. Is it really need to correct so many months?

The article got changes now and there is progress with the abbreviation

but still in mintage section gives
2002 J 0.2% Variant 3 [0,02%]

Note. Obviously the percentage is from wrongly described occurrence of lines and has nothing to do with frequency as it expected to be. This is not the case of this topic.

Recommendations:
1. Explain the personal note 1 Variant 3 in the comment in the same field or in Comments section.
2. Explain the personal note 2 [0,02%] in the comment in the same field or in Comments section.

Oh Boy
