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
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
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?
