it may be worth noting that there is a community-created page that has optional functionality to let you know whether you are the top observer of taxa: https://forum.inaturalist.org/t/sort-your-observations-by-least-observed-globally/34626/6.
i don’t necessarily endorse its use since i think the general process required to get this data is super inefficient (see the discussion referenced in my earlier post), but some folks might appreciate it.
