Some of my observations, with a ~5km radius circle (1270 observations at time of posting), the centre blank: https://www.inaturalist.org/observations?lat=51.30376895574157&lng=-0.18203753804374667&radius=5.648424553017703&subview=map&user_id=jamie-aa&verifiable=any
A circle with the same central point, radius about ~1.25km, showing 12934 observations (should show 0): https://www.inaturalist.org/observations?lat=51.30376895574157&lng=-0.18203753804374667&radius=0.6307093643525782&subview=map&user_id=jamie-aa&verifiable=any
Screenshots of what you are seeing:
Big circle (note the area around Chipstead has no observations at all). I haven’t counted exactly, but that number seems right:
As soon as the circle is shrunk to the observation-empty area around Chipstead, it gains ~11,000 observations, instead of showing 0:
For another example, I have no observations (or obscured observations that could show there) on the Greenwich Peninsula in London:
But putting a circle that covers it shows observations from across the city:
Once I make the circle bigger (about ~2km), it shows no observations, as it should:
My observations mostly do not have accuracy radiuses, but this doesn’t seem to matter - this bird observation https://www.inaturalist.org/observations/298659543 shows up, despite the accuracy circle being 84m (way too small to overlap), with the search circle being about 8km away and only covering a small bit of the Thames:
Description of problem:
Step 1: Create a circle with a small radius (less than 2km?).
Step 2: Notice that you’ll pick up observations miles out from the circle’s radius. This doesn’t seem to happen with custom rectangles.
Step 3: Expand the circle’s radius. Once it’s big enough, it’ll search correctly, and show you only observations within the area.
