“Finer” maybe was the wrong word to use. “Specific” would better describe what I’m getting at.
E.g., when I first started iNat, I didn’t know that cranes and herons were in completely different orders. So if I IDed something as “Cranes, Rails, and Allies (Order Gruiformes)”, and someone came along after me and IDed it as “Typical Herons (Subfamily Ardeinae)”, I’d just assume their subfamily ID was a refinement of my order ID…when in fact it was an explicit disagreement.
