Reliably means close enough to be useful, but the estimation is also quite precise where most populations live. My use case which led me to discover this fact

Reliably means close enough to be useful, but the estimation is also quite precise where most populations live. My use case which led me to discover this fact is sort of documented here: https://twitter.com/mholt6/status/1695685022710477043 https://twitter.com/mholt6/status/1695685022710477043 -- even if my use case did have whole kilometers of displacement, it wouldn't likely be near the poles, and if it was, the answer would be, "Meh, we get it, you're at the pole."
