How rare is it?
One page per number. Each one says what share of people are below it, worldwide and by country or age group where the data allows, and how many people you would meet before finding one at or beyond it.
The percentiles use the same distributions as the tests on this site, so a result there and a page here agree. Every page names its source and year. Where the sample is a self-selected one, such as people who take reaction tests online, the page says so.

Percentiles are estimates from a normal distribution with the stated mean and standard deviation. They describe where a value sits in a population, not whether it is good for you.
