The following users have won the Couch Potato Geohash Achievement. This achievement can be attained only when the place where you live is exactly under the coordinates of a particular day. This is incredibly lucky, and the chance of this happening to you, is the area of your domicile divided by the area of the quadrangle you're in. Assuming a spherical earth of radius R (Earth is approximately 6378km), ϕ = latitude, and H = the size of your domicile, then the probability P is represented by the following formula:
A typical apartment dweller in Denver, CO, has a chance of around 9e-5; a bit worse than one in 10,000.
If this does happen to you, you are required to throw a mad-keen party at a day's notice.
This is one of those things that probably won't ever happen, but how cool would it be if it did?
