No doubt about that (even then, you will probably want the 90 or 99 percentile, depending on how many interactions you expect a person to have).

Th real median is just very hard to measure, and an easier 99.99 (with more 9's as needed) rank is almost as good.

Can you say more about why you say the "real median" is hard to measure? It doesn't seem hard to measure to me, or any harder than a 99.99 percentile. Why is 50th percentile harder to measure than 99.99th?
