I'm sure the "c", "b" and "q" numbers must mean something... anyone seen Jeff lately?!?
That's the way it struck me - a bizarre mathematical construct to serve a somewhat similar purpose to the buttock lines on a hull drawing

I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
