GIA can not endorse anything (nor MSU) until they have completed all their exhaustive research. Once stated they will have severe difficulty retracting any statements. I neither look for nor expect GIA endorsement and hold their approach to this issue with great esteem.
As you know they published the results of the Brilliance study 2 years back and look at the storm of missunderstanding that created (including some of my own published comments). They are very wary of any future communications, although I do from time to time have embargoed discussions with researchers there (but of course no comments about HCA).

AGS - now that is another issue. In personal communications they know their system is flawed. They were attempting to do something about it, but I think they have decided the business is too good to give up and they will slug along until the GIA conclude their study!
Personally I believe that is inappropriate for a proffessional and trusted body.
Do I seek their endorsement? I think not. Do they seek mine? I have been asked to be patient, but anyone who knows me knows that is impossible!

No Steve you missed nothing - there have been no annoncements as yet.
Yes we are working on a stand alone program that will hang off any source of data, like Sarin - or allow manual input. This includes girdle (and min-max), culet size and eventually symmetry, half facets and polish.
But like you Steve I run a trinket store (2 actually) and this is work that happens inbetween.
