I looked at some of the other links on that page and found a few things that don't set quite right with me. The GRE to IQ correlations they list completely leave out the analytical section which I do believe has been eliminated, but did correlate fairly well with "g" in that it was a test of analytical reasoning, patterns, and visual spatial measures.
The "occupational IQs" chart that purports to list the range of IQs of people in various professions rubbed me the wrong way honestly and not b/c I am a janitor
. (I'm not.) There is no way to say that the full range of IQs for truck drivers, for instance, begins at 76 and ends at 109. I've known truck drivers with PhDs who are a lot brighter than 109, but who were introverts who found their place on the road and away from dealing with people all day. That career line, in particular, probably has a much, much broader range of IQ than listed there.
I do take your "FWIW" as a disclaimer, though!
