@Xaser:
From my understanding the table just seems to show the.. variance (?) of chords in each entry (so, like, how often different types of chords (or notes, I'm still not sure) are used)).
Should you care? ...well, if you don't think it's a problem, then probably not. Personally Xaser (from what I've heard of your music so far), you're doing just fine on the chord front. If you feel like you do wanna make your songs a bit more varied in terms of chord progressions, then doing stuff like playing around with different note combinations and stuff in yr tracker, toying with dissonance more - seeing if you can work out some new ways of voicing chords. But yeah, if you get an unhealthy rating it's no cause for concern really (especially as this is essentially a program running some code).
I think musical analysis has always put a very heavy emphasis on harmony... perhaps too heavy if you ask me. While there may be certain "do's" and "Don'ts" with regard to harmony it can be easily made up for in other areas. I like plenty of songs that use, like, 2 or 3 chords, or even less. But yeah, using lots of chords is not the be-all and end-all in music.
