Re: Fibonacci
"Targets are discrete, countable units. You have more of them or you have fewer of them or the number of them is unchanged."
Oh, you want to be a pedant, do you? I claim that targets are neither discrete nor countable. As a proof, I must demonstrate an uncountable continuous region of targets. I take 'the pass rate must be n%' as my region. Firstly, since percentages are real numbers this yields uncountably many targets, so your first point is wrong. Secondly, I can place a natural topology on this space homeomorphic to the interval [0, 1] under the usual topology, so the space of targets is naturally non-discrete.
