Then perhaps lean to write. If you're measuring a different
phenomenon, one that has different units, then it's a distinctly
different *calculation* becuase you're measuring a distinct collection
of objects. One may as well add up a restaurant bill, leave out the
tax and tip, and say "it's unchanged because I used the same plus
It's particularly confusing, as the original poster was confused, when
trying to comparae "prices", in this case system loads.
