I’ve made a few graphs on an online graphing calculator showing the average amount of species per observation count:
https://www.desmos.com/calculator/88z8zalsne (Including casual observations)
https://www.desmos.com/calculator/qwgzfnblxm (Verifiable obs only)
https://www.desmos.com/calculator/z0id72zjap (RG obs only)
https://www.desmos.com/calculator/labvyvssep (Verifiable, to species level)
You can put your observation and species counts (include casual, needs ID, and/or RG observations depending on which graph) into the table and see how you compare to the average. I’ve already put my stats in, and it looks like I have less species than the average person with a similar observation count to me. However, that is all that means. It isn’t really a metric of how valuable your observations are, but more like a fun comparison.
