thanks Dason! nope, i'm not saying there's anything wrong with using it with a point estimate. i'm writting chapter #1 of my thesis now and just wanted to throw out the claim that bayesian estimates can also achieve efficiency under the CR bound. but i stopped myself before writting that because, to be honest, i'm not sophisticated enough (yet) to understand the link between the inverse of the fisher info and bayesian estiamtes so i just wanted to make sure that, at least in some cases, this holds to be true so i can write it down in my thesis without the fear that someone (like the Cauchy Distribution) will come down and get me...
