Rans have a search for BEagles posts I am sure his background will answer your question.
As your in Cov why don't you go and have a hour or 2 with one of the FII's at Ontrack at Wellsbourne most of them are ex Mil QFI's or do the CRI course. You can debate the pro's and cons to your hearts content with them about a whole range of habits. I would throughly recommend them to anyone.
