normally i would point you to the iNaturalist API to get at least up to the top 10,000 records in such a list, but the observers endpoint doesn’t seem to want to give me results past the first page right now (ex. https://api.inaturalist.org/v1/observations/observers?per_page=500&page=3). so then if that doesn’t work, i don’t think there’s a good way for regular users like to find your position, if you’re not in the top 500 observers for a particular set of parameters.
