I worked on some real-time data acquisition applications at the University
of Illinois between 1980 and 1984, and if my program wasn't ready to read
that data word and put it someplace appropriate when it was ready to be
read (affectionaly known as "overrun"), we had to throw out the whole trial
and do it over again.  Some of the experiments I assisted were simple
enough, but most were not easily reproducible (particularly the ones
dealing with muscle fatigue) and I never again want to suffer the wrath of
a grad student facing a grant or thesis deadline.  Like the original
article said, if it's late, it might as well be wrong.
