Incorrect guitar chords

[hovi]

Hey,

I liked this db and decided to use it in my app. I found however, that there are some mistakes in the database. I created script, that checked fingerings against what's in database and this is output I got. Some of it may be just cause you have different naming of chords or I have some of chord rules wrong, but there are definitely errors. I am excluding problems with missing perfect fifth as that is pretty common thing to do. Also I haven't checked all chord types as I don't have them in script. In case of interest, I can keep on updating this output or change it's format as I add more chord types to my app. Anyway, there is my output:
