Well, it would be higher except that it IS still considered inappropriate to zap a replacement clone for something his or her predecessor did.  Just because Dumb-R-GUY-1 was a mutant is no reason to suspect that Dumb-R-GUY-2 is one as well, nor does Dumb-R-GUY-2 know any treasonous stuff Dumb-R-GUY-1 observed before getting Zapped.<br/><br/>If those two rules were not in place, no Zap! mission group would ever reach Briefing.
