Yes, that accuracy value needs to be smaller in order to appear on a map. The cutoff for that number changes with latitude, but I think it’s around 30 km at the equator.
You can search specifically for observations that are RG and have large accuracy values using a query like this: https://www.inaturalist.org/observations/identify?quality_grade=research&acc_above=30000
If you’d like to make a feature request, please submit that separately from this thread.
