Hi

I’m still experimenting with grade and sd statements..

I can get some very extreme distortions with just a small relative difference in sd values.  No problem, it’s just a function of my mis-close, and the math.  To my advantage it may help me to decipher the scope/visibility of grade statements if I can concentrate on the problem long enough. 

I finally took the hint in previous postings that BCRA grades 3 & 5 might be built into Therion.  I tested it and indeed they are.  Is this documented anywhere?  Would have saved me quite a bit of experimentation (and embarrassment).

I’m still looking for a ‘best practice’ on where to put grade statements and how to control their scope/visibility.  Perhaps someone could write a brief note for the Wiki or the Therion Book?
