It's just my opinion, but I would think that until you've got almost all of your other leaks plugged, it's probably a wasted effort to get more accurate than the rule of 2 & 4. Most people aren't inclined to do that much math in the middle of a hand when these approximations get you pretty close. Probably the easiest thing to do is to examine the charts, and then keep in mind that you have to "add a little extra" to your probability as the number of outs goes up.
