there's a 50% authorization.  From a conditional probability

I agree that the assignment of 0.1 to ? is arbitrary.
Perhaps ? should
continue to mean SOFTFAIL and not have any probability
assigned to it.
Or perhaps it has probability 0+, or epsilon, for some sufficiently
small value of epsilon. ;) 

I have ~ and ? backwards above!  Apologies.  tr/~?/?~/
