No, this could never happen, even if you change it. 2/3+ concensus is a requirement for RG.
No. The first choice here does NOT give RG as subspecies. It gives RG at species with a Display ID of subspecies:
The second option in both cases is an Explicit Disagreement, and effectively nullifies or forces the other ID to be treated at the agreement level (species for the first, genus for the second) as far as calculating CID is concerned. They are the iNat equivalent of being able to vote in an election and also claim that the person who voted before you is an idiot for voting for someone else, and that that vote should be disqualified. [Apologies for expressing my own personal dissatisfaction over how explicit disagreements are handled!]
Another requirement for RG is that the CID must be finer than genus (ie sub-genus or better) OR be at genus and have “ID is as good as it can be” set in the DQA. The reason the second example goes to Needs ID is because the CID becomes genus, so doesn’t meet this OTHER requirement! You can test this out by setting “ID is as good as it can be” for the second example, and it will become RG at genus.
To be a “double standard” it would have to be a difference of how two otherwise equal things are treated. Subspecies as a taxonomic level is not the same as species or genus… every taxonomic level has it’s own set of “rules” that relate to it. A double standard would be having the same taxonomic level treated differently under animals vs under plants, for example. If you consider “taxonomic levels” to be equal things, then it’s a double standard to say two species level IDs = RG when two family level IDs can never be RG. The RG label is all about the differences between the taxonomic levels!
