Greg,
Sorry , I missed that.
You know, personally, I don't use the "contrary" and "same" convention.
Years of math by hand trained me to watch out for signs when
adding and subtracting - got bitten too many times. The advantage is,
of course, one doesn't have to remember special sign rules.
My choice of letters was simple:
N: negative as in L-D, P: positive as in L+D; Q: well, next after P :)
Boy, what a compression of formulation, though - I am so happy about that!
