Bye There is an important omission in the calculations for the "Constraint Analysis". Put there on purpose to see what would happen. All of the calculations are simple "hand, closed-form" calculations any high school algebra student should easily follow. Since no one commented on any of them, I think either no one bothered to look through them or no one has the expertise to understand them. Either way this is my last post. I'm sure the "good ole' boy" club will pointlessly blabber on and on about any and all of my attempts to bring a small amount of order to what has to be the most random assortment of opinions I have ever experienced. Since I don't fit in to this culture, I will welcome it as a badge of honor to be exorcised from HBA.
