For the  Gaussian one, probability drops off so quickly, that very soon better interventions are so rare that aren't worth looking for. <br><br>Much of the difference in shape (eg Gaussian being symmetric) is irrelevant to this point, so the example is unnecessarily confusing. You could use a Gaussian centered on 0 where everything below 0 is cut off, and the relevant difference would remain. <br><br>(I was surprisingly slow to get this last night.
