The methods may not be "real life" but as long as they test all brands the

Correct.

I have to agree with Richard on this one. There is no way anyone can
say that, because the EPA test standards as Richard provided, do not
test the refrigerators anywhere near to how they are actually used.

That's not really particularly relevant -- the point is that two units,
_if used the same way_, will have a _relative_ efficiency factor between
each other that is reasonably well approximated by the test. The
absolute values aren't significant; it's the relative change between the
two that is compared. And, that variability is precisely why the
testing doesn't make some arbitrary cycling patter--it isn't really that
important for the purpose of the test.
