Marking ‘yes it can be improved’ when unsure

Like @paul_dennehy, I appreciate your explanation of your thinking for using the “Yes, it can be improved” option. But the caution others have added is most appropriate: To most of us, and the intent on iNat I think, is that that particular DQA be reserved for cases reviewed by people well-informed of any particular ID challenges with a species or set of species. In such cases, a vote for “No, it’s as good as it can be” for a genus (or higher)-level ID is a mark of a taxonomic “brick wall”.
