To BDAZ's and GP's points regarding BKC's question, I have previously asked the company why these presentations are not done with a company scientist online to field such questions.  I have never received a response.  To me getting science questions answered by a non-scientist, or even doing the science potions of the presentations, does not have the same impact (or clarity) as having a qualified scientist handle this function.  Other biotech CEO's who are not scientists do this as a matter of routine, the optics and answers are much more impactful.
