But then it is not a model, and the benefits of modeling (exploration
before building the real cat) are lost.

Hi Scott,
No worries. I guess we'll just have to agree to differ. We couldn't get
a good correlation with Hammerstadt using measured microscopic
parameters, which suggest to me at least that any macroscopic fit is
fortuitous.

Not ganging up on you at all. Just ganging up on the fact that the
"Intel/Huray" approach of performing this level of microscopic detailed
modeling is gross overkill. I'd certainly love to see good complex
correlation of both magnitude and phase for the Huray model in a
simulator. But, it's just not necessary, having done hundreds of models
correlated with measurements using the Djordjevic-Sarkar model combined
with the Hammerstadt-Jensen model (or other macroscopic model).
