It's probably best not to, since it is a linear improvement to an exponential problem. Where the real improvements in playing strength will come from are exponential improvements to the exponential problem (like null-move knocking that branching factor down). Of course, I'm sure you already know this, and this is your clever way of making others think about it for themselves and discover the answer on their own, giving us all a greater sense of accomplishment and self worth (not to mention saving us a great deal of time) ;-)
