Counting bits has one major use. When someone in future is skimming 
thru your catalog looking for samples of specific materials the 
number of bits, combined with the overall weight, provides clues 
about what to expect in a specific bag. That may help them to decide 
whether to pull that specific package of bits right now, later, or 
not at all. And a minor use - if/when vandals (or a tornado...) hit 
your storage area, you will have some idea which bits were originally 
packaged together.
