My biggest bugaboo with AA is not publishing PDFs of the catalogs they are using. They list them, and in cases where a catalog they cite is available somewhere else, it's possible to doublecheck their analysis, but if they have a catalog nobody else does, there is no way to confirm their analysis. That wouldn't be a problem of their analysis was always solid. Unfortunately, it's not. Second biggest issue is not always explaining their rationale. Third is their refusal to accept and use references (catalogs, ads, other research material, etc) they don't own and analysis they didn't perform themselves. Between their library and "ours" (public domain, TA 1.0, etc), we collectively have a very comprehensive library, but there is no way to conduct complementary and supplementary contiguous research and analysis without seeing their catalogs. Fourth is just not being receptive to corrections. All of that is why Todd started TA 1.0, why we're working on TA 2.0, and why I will never send AA a dang thing again in my lifetime.
