Dear Brian and fellow flownetters,
     
This scheme reminds me of a local radiologist who writes in his reports that 
the "ICA has a 43% stenosis while the common carotid has a 67% stenosis". 
Whew, I must be slipping but I can't massage my QA enough to get either of 
these methods to work for me.

This reminds me of the worried surgeon that came up to me at a meeting  asking 
for advice because his competition reported out stenoses as "62.72% (yes folks, 
to the hundreth of a percent - I saw the report he had) and it makes us look bad
as we give the range of 50-79%"  Bottom line - it matters less what criteria you
use and more that you have the internal validation to support it.    Bill / Fl
