The expert IDs aren’t usually going to species, but I think the point @sbushes is trying to make is that those experts are providing a more refined ID (e.g., to family or superfamily) and it’s not paying off because it gets hung up at just Opiliones, because of the maverick spider ID. So it’s a bigger fraction than 3/30. I count 16/30 that are affected currently (i.e., have an expert ID below Opiliones but also have a maverick spider ID that is keeping it stuck at Opiliones no matter how many people agree it’s Opiliones).
Is this “niche” compared to the firehose of observations that iNat gets? Of course. But that doesn’t mean the algorithms can’t or shouldn’t be improved.
