I really don't think that's it - I think that sometimes a data table is
just a data table.  There are some coding styles that work to avoid
having raw numbers anywhere in code outside of defines at all costs but
I do think that goes too far in cases like this where the name of the
define is at some level just going to summarize what should go in a
given slot in a table which adds little.
