When I was young, I found that generally available IQ tests were inadequate. Every test has a range, and accuracy decreases as you approach either end of that range. If someone tests extremely high on a typical test, they should be given a more difficult test with a higher ceiling to get a meaningful result. Ron Hoeflin made such high-ceiling tests, although they are inherently difficult to norm because the elligible population is vanishingly small.
Decades ago, I was tinkering with Ron Hoeflin's "Mega Test", and though I never sought official scoring, I used it to estimate my IQ (using a 16-point sigma) at around 176 at the time, which has a rarity of about 1 in 1,000,000 people. A few years ago I used Hoeflin's "Titan Test" similarly, and my estimate then was around 172, if I recall correctly, which is about 1 in 300,000 people. The ravages of age have since, I suspect, ruined me. It is harder to concentrate on anything for very long now. My laser-like focus is gone. I feel muddled, and painfully aware of what I have lost.
As for feats of intellect from my past, I will have to keep them to myself. I have a personal policy of not saying anything that could be used to narrow down my identity. They're nothing too impressive though, so you're not missing much. It would be hard to find another person who did so little with so much.
