I'd expect the distribution of values to be closer to a power law than the Normal distribution -- at very least a few states would have the most lookups. But this is my gut feel, not based on any scientific analysis!
G'day and thanks! (I'm in the country to the left of you....) Yeah, and my mocked data divides things up fairly evenly :(
I meant to mention that when I did my tests that I only had one index on at a time to prevent confusion. I also ran the speed tests several times so each was on a warm cache.
