The law of diminishing returns in micro-economics. That law must apply in
device characterization the same as in micro-economics but I never seen
anyone published anything rigorous or scientific about it in device
characterization. Seems to me everyone goes about characterizing using their
own heuristics. I agree some higher number seems in order for less than
ideally behaved devices. But exactly how much? It's hard to tell. And not
all CMS packages support "extended" targets. ProfileMakerPro and Monaco do
support such extended charactization scheme.
Also, itIt is entirely possible that some CMS packages could do better than
others using the same amount of measurements. As Grame indicated earlier,
the degree of modeling is an important part of the equation too. And, as you
say Marco, as long as the extra data is over and above the inherent degree
of imprecision built into the instruments then it's all worth it.
For my part, I have to confess that I have not experimented with these
extended techniques to date. So I can't really say what kind of marginal
precision can be gained. Although I tend to concur with the opinions of
Terry and Grame and others that "more" is "better", to a certain extent and
in certain situations. I don't see it for press profiling. Let's get that
out of the equation.
