Whendensity of precipitated slurry is too high, becauseof the collisionamongparticles, bigspindlyaggregates which are made of ultra-fines are born in reactor at the action of surfaceenergy.
Anything lower reduces the expected cost of criminality, without doing anything to improve the probability of detection. (Treating whistleblowers leniently is consistent with this logic: letting them off punishment raises the odds of truth-telling, and therefore of detection.) There are plenty of arguments against ultra-high fines, however.
