Bernoulli trial is applicable to coin tossing because there are elementary outcomes known to be independent. That was the fist question I asked, what are elementary event in the experiment of SW developing. How are they independent etc. You cannot apply mathematical statistic without probability axioms satisfied. Until there is no convincing explanation of how this could be done in the case of SW development, all this is nothing but pseudo-scientific numerology. -- Regards, Dmitry A.
