THE MISERY INDEX.
That's interesting, but not especially useful. Maybe the following will help you know how often to expect an unfavorable
flop. It tells you how frequently the
flop will not provide you with at least one more of your
rank (thus making three-of-a-kind or rarely four-of-a-kind) AND the
flop will contain at least one card higher than your
pair. Based on that simplistic assumption, this is the "Misery Index" taken from my Professional Hold'em Report . ..

While this chart is deliberately elementary and ignores many concepts critical to professional hold 'em, it nonetheless illustrates a profound truth. There isn't nearly as much difference between low ranks as there is between high ranks. Look at it this way. A
pair of kings is much better than a
pair of queens (and they're only one
rank away from each other), but there's a much less dramatic difference between a
pair of sevens and a
pair of deuces (five ranks apart). Also, notice that, based on the simple premise, you're probably going to hate the
flop unless you hold at least a
pair of jacks. Good night.
