So the real problem is the length
of time it would take to do a real-world double blind test. It is
pretty impractical.

What are the time limits in a PCABX test?

You're still not quite getting the point.

You're not answering my question.

http://www.pcabx.com/ See "properly designed" listening test.

There's 10 items on that list. Referencing the whole list and then not
addressing any of the points seems like a pretty strange thing to do.

My point is that IMO their
idea of "properly designed" is completely wrong when it comes to
realizing differences in sound that become important to you over
time.

That's no problem at all. Items 2,3, and 4 specifically address your
concerns.

This isn't a math quiz.

Of course not. In math quizes there is basically a time limit. There's no
time limit at all in a PCABX test. Furthermore, listener training sessiions
are the logical lead-up to the test of the final hypothesis. They can go on
for as long as they need to, as well.
