Not true. You can represent ANY density by any number of bits. I can
represent an entire density range with two bits:
00 - at or below dMin
10 or 01 - between dMin and dMax
10 - at or below dMax
This is a completely valid encoding of density range.
I have to run now, so I'll comment on the rest of your post later.

Austin
