No one has answered his base question yet. Does anyone here know the answer?

Of the number of shakers assumed/calculated to be encountered, what percent of those are assumed to die from the encounter. Anyone?

Do they figure 10% die? 50%? and how does this assumed mortality rate on shakers figure into our allowable impact?
