When you manually upload your observation from your laptop or PC and then type in the location of your finding, it is important to pin and narrow down the place as accurately as you can. Why? Because that will give the scientists important clues as to the organism's habitat and the exact topographic conditions that it thrives in or has adapted to.
There are areas of wooded slopes alternating with rock-outcrops bordered by meadows, all in close proximity. If you cast too wide a circle on the map, we won't know if your taxon lives underneath the trees or among the grasses or if, perhaps, it clings to a rock face, because that might not be evident from your photo(s) alone. (This, of course, applies mainly to stationary taxa, like plants. They don't move around like critters do ...)
You might also want to mention a characteristic or two of the habitat / surroundings in the Description box of your listing, along with other remarkable aspects of the item under observation. But most folks don't want to bother taking time to do that... all the more reason to peg the location precisely.
And then there is one other consideration: Some of your fellow iNaturalists in the area might get so excited about your discovery that they want to go see it for themselves. So, be kind and neighborly, and show them on the map exactly where to find it.
