Well i'm seing something wrong here.......

At your site you have that CRC positions should obey to this rule:
c) compared to the initial array of GC at least three squares have to be differently filled;

And now you are saying:
Skip this position if it has at least three positions in line 1 similar to Gothic Chess.


2 things i see wrong:

1)You should replace "at least" in what you wrote here, with "at most". At least 3 means: 3 or 4 or 5 or....10. At most 3 means: 3 or 2 or 1 or 0. So you should obviously skip positions which have 3*** or 2 or 1 or 0 squares filled differently. So you should replace "at least" with "at most".
***=actually the 3 is wrong also and this is my second note.


2)You should replace at most 3(having already corrected the "at least" with "at most"), with at most 2. At your site you say that a position should be legal only if it has at least 3 squares differently filled. That means if it has 3 or 4 or 5 or...10 squares differently filled, it is legal. So it is illegal only if it has 2 or 1 or 0 squares filled the same. So we should skip those positions, so we should skip every position that has at most 2 squares differently filled.
