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.
