Tim,
my personal preference always was I/sigI=1. In my Scalepack days, I
always noticed that ~30% of the reflections in the I/sigI=1 shells had
I/sigI>2, and formed an unverified belief that there should be some
information there.
In my experience, CC1/2=0.5 would normally yield I/sigI~1, not 2. This
is based predominantly on Scala/Aimless.
Cheers,
Ed.

I don't know why the sacrifice thing didn't work.
Science behind it seemed so solid.
