Well - how many do you see when things are operating nominally?
How many do you regard as "the other end is obviously too crazy to listen to"?
Add them up and divide by two.
Of course, the hard part is quantifying those two values - the network
engineers for the AS I work for probably have a different tolerance level for
such shenanigans than the guys running a Tier 1/1.5/more-than-2 network (and
*those* guys almost certainly have different tolerances based on which of their
peers and transits they're talking to)....
