Most anti-Darwinians, when using math, utilize strawman arguments, and this is usually quite obvious. For example, Hoyle's original 'impossibility calculations' (the so-called tornado in a junkyard scenarios) were totally irrelevant as he calculated the odds of all things happening at once - that is, for example, a complete functioning cell popping out of its constituent molecules in one fell swoop.
Of course that is impossible.
It is also wildly misrepresenting evolutionary theory. Dembski has done the same.
