I was going to answer this but IMO you know the answers as well as I do. Your point 7, reiterated in your post this evening, is the real issue that you seem to have (and one that has been discussed ad nauseum on Rootsweb). They are not going to reveal exactly what they have done or publish the specific AIMs for your benefit as this is proprietary information. As Doug says we might expect to see some discussion in relevant journals. The company has previously said that they want to expand their population samples, amd we can reasonably expect this to be an aspect of the version 3.0 development. In due course we will all have more details.
