Me neither, but I was just guessing, and when I said "older" I meant, like,
pre-1970. I kind of think one of the Gordon Bell books talks about margin
testing and K.O., like maybe that was his thing back when he was actually
an engineer himself (i.e. 1950s?). But I haven't read it in a while so
I'm probably remembering wrong.
