I yield to your superior knowledge of statistics (I have none), but that's not the point. Layoffs are about speed, not accuracy. The faster they're done, the less damage they do. The only thing that matters besides the number of people to lay off is not losing your best people, which comes down to speed (the longer the mess lasts, the more likely your best people will leave) and being accurate enough to not accidentally lay off your best people. Seems to me that stack racking, however awful it is ethically, emotionally and statistically, at least covers that well enough.
