Okay.

This makes more sense.  Pre-define overlapping partitions but only use 
non-overlapping.  Sort of like tool boxes that come with a bunch of 
supports for dividers, but you can only put so many dividers in the 
pre-defined spots, but contents between the dividers doesn't overlap.

Sort of like how many squares are in this bigger grid of dots that is 
itself a big square.
