On the basis of Terman's findings it may be estimated that fewer than 1/10 of 1 per cent of school children are to be found at or above Binet IQ 160

This is simply not true. In normal distribution with mean = 85 and SD= 15 the probability of having 163 IQ is so small, the calculator returns zero. Being 130 and above approaches 0.001 probability. 119 and above is ~0.01. For 160 it must be incredibly small number. For IQ of 200 even smaller. I'm not even sure if such IQ can be measured on IQ tests. Whatever scale Binet was using it is not the same as current one.

Marilyn vos Savant has an IQ of 228. Yes, it is very rare to have 160 + IQ. No, the calculator does not return 0.

Alan S. Kaufman, a psychology professor and author of IQ tests, writes in IQ Testing 101 that "Miss Savant was given an old version of the Stanford-Binet (Terman & Merrill 1937), which did, indeed, use the antiquated formula of MA/CA × 100. But in the test manual's norms, the Binet does not permit IQs to rise above 170 at any age, child or adult. As the authors of the old Binet stated: 'Beyond fifteen the mental ages are entirely artificial and are to be thought of as simply numerical scores.' (Terman & Merrill 1937). ...the psychologist who came up with an IQ of 228 committed an extrapolation of a misconception, thereby violating almost every rule imaginable concerning the meaning of IQs."[13] Savant has commented on reports mentioning varying IQ scores she was said to have obtained.[14]

The second test reported by Guinness was Hoeflin's Mega Test, taken in the mid 1980s. The Mega Test yields IQ standard scores obtained by multiplying the subject's normalized z-score, or the rarity of the raw test score, by a constant standard deviation and adding the product to 100, with Savant's raw score reported by Hoeflin to be 46 out of a possible 48, with a 5.4 z-score, and a standard deviation of 16, arriving at a 186 IQ. The Mega Test has been criticized by professional psychologists as improperly designed and scored, "nothing short of number pulverization".[15]

This calculator is set to mean of 100. Blacks have mean of 85. While some individuals like that may exist, it's extemely rare

I know, which is what makes these case studies interesting. Maybe not to you, but I'm curious about what differences they have from 160 + whites based on different evolutional pressures.

Jensen wrote about differences between low IQ blacks and similarly low IQ white if that would interest you. Bu I'm not aware of anything written about high IQ individuals. Likely because getting meaningful sample size on that is nearly impossible.
