Hey David, 

my answers are delayed here, although I am not using my gmail email

Yep thats right, those bands of zeros are one of the most important values
to define one group, and have a nice distance from the rest of the groups
:). I cannot really get rid of those, I bet it would not help if I would
change all of them to a really small (but same) value.
