This should give you'all a fair appreciation of the extreme importance of the exactitude of these measurements, and how important it is in daily usage that these requirements are met.
My trusty mentor in basic telephony, a gentleman of Jamaican descent, used to say: "The world's telephone systems were not designed, they evolved. They can stand a bit of buggering but not everybody can bugger them all the time". Hear and listen all ye exactitude freaks. I must admit that Ronan also had a standard retort whenever his wife told him he was doing something that was unwise. "Woman, McGill University gave me an engineering degree and therefore you should give me credit for some brains". This led to some of my colleagues of the female persuasion making sure none of their sons would ever go to McGill. Ciao, Vic
