Something seems to be off with the observation and species counts.
I use iNaturalist in my classroom and so I look at student observations and they are supposed to make a certain number of observations but the number is different in several places.
For example, I will use a student example. At https://www.inaturalist.org/people/wachnin you can see that it says that the student has 15 observations and 6 species. But if you click on their observations it says 12 observations and 11 species.
I keep track of their observations in a project at https://www.inaturalist.org/observations?project_id=83623&ttl=120&v=1600533510000&place_id=any&verifiable=any&view=observers that captures all of their observations and it says that the student has 13 observations (I can understand it if had less because of non-wild observations but not more).
The actual number of observations is 12 if you count but not sure why it is not correct in the other places.
I have been grading my students observations this week and this is just an example. I have observed this problem with several of the observation numbers and so it is definitely not a one off.
