Hmmm. I think I would like to be more cautious. I think there are
different levels of worries:
- Having a criterion fail often in practice is worse than having it fail
more rarely in practice.
- Having a criterion fail rarely in practice is worse than having it
fail more hypothetically (than actually).
- Having a criterion fail hypothetically is worse than not having it
fail at all
Now there are some criteria that aren't important to me at all, that I do
not value what the try to protect - and those I factor out. But in
general, I am going to try to be very aware of the nature and prevalence of
the unpleasant results that violating criteria can bring.
In other words, until a particular system's violation of a criteria is
clearly demonstrated to me to be insignificant, I shall instead adopt a
worst case approach. ;)
