I feel the need to be pedantic here, because your post makes a couple simplifications in the same direction that skew the results by roughly an order of magnitude.
145 is the top three tenths of 1 percent, not the top tenth.
The average high school size in the US is 854 students [1].
In an average school, you would expect there to be 2.5 students with 145+ IQ.
The largest school in each state is about 5-10x the average size school for that state. Let's call a large school 3x average, then.
In a large school, you would expect to find 7.5 students with 145+ IQ, or roughly 2 per graduating year.
"About 8" and "Maybe 1" are almost an order of magnitude apart.

- jeffbee 5y agoReally? I thought that std. dev. was 15, so 145 would be the .9987 quantile, which I abbreviate to about the top .1%. If std. dev. is 16 then it's the top .25%. But we agree on the bottom line: 145 is not rare. You might know someone of this IQ.
