The technical definition of a "percentile" in statistics is taken from the quantile function; it is the value below (or below or equal to) which a given percentage of values falls. For example, the 20th percentile is the point where 20% of values fall below (or below or equal to) that value.
However, in a previous answer to a question here, I got into a little debate with other users about whether or not there exists an alternative practice of people reversing the meaning of "percentiles" so that it now refers to a value above (or above or equal to) which a given percentage of values falls (e.g., when the writer refers to the 1% "percentile" as a cut-off where 1% of values are above that level). Here is one example of the reversed usage in an article in the Wall Street Journal. We came to the conclusion that this practice does exist, but now I would like to try to get a sense of how common it is. So, let's collect some data (albeit non-systematically).
My question: Can anyone identify other examples of this non-standard usage? (I.e., examples where a source refers to a "percentile", but uses this to refer to a value above which a certain percentage of values lie. More authoritative sources are best, but I am interested in any published examples.
