Ian,
Now it's still true that Ncon reduces Npar but it's no longer true that Ncon increases Nobs.
This seems counter-intuitive enough for me to ask a stupid question: which parameters are being removed in restrained refinement?
For constraints this seems straightforward (transformation of >1 parameters to 1 parameter); but the same logic doesn't appear to apply to restraints (at least, I can't figure out how it would).
Pete
