No, the bottom line is that the rate of use in aviation is so low (as
indicated by the results) that most if not all of the positives are
false positives. If it's worth doing, it's worth doing right - and
since nobody seems willing to spend the money to do it right
(eliminating the false positives) I have to assume it's not worth
doing.
