I was invoking Lord Kelvin's principle. (Yeah, the temperature guy. He also did electronics.)I have no idea how much he plays or just how cheap and dirty he let's his balls get.
I can't answer your question...but I can't tell if it even was a question or you were disagreeing.
“When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind.” -- William Thompson, Lord Kelvin
