sorry :)  that would be the probability of certain bit patterns (bpermd)
staying out of the top range.

one of the intermediary numbers used in the pseudocode is not the right
bitsize, but unfortunately it's created "automatically" (an intermediary).
it'll take some investigation to track down, so i left it for now.
