all we needed
was a tangent on flooring vs truncating. :)
If you truncate the TC I'd guess -0- is the correct answer, period, since that makes TC=0 twice as wide as any other count.
If you floor, I'd take my "between -1 and 0" to be pretty close.
But as I said, these were "gut feelings". And more often than not, as BS has shown, "gut" != "right" (!= is computer-speak for not equal of course).
I did so well on Eliot's 30 card question, I had thought I had busted this one badly also. :)
