Flippin' weird: Is it just me, or is Mammendorf is just as preferred by the random (?) Geohash algorithm as the surroundings of Munich's airport? 2008-07-23 48 11 2009-04-03 48 11 Map of 2009-04-23 Map of 2009-04-23 --Zb 20:07, 23 April 2009 (UTC)
- I believe noone has exactly examined that yet, but basically those repetitions seem to be an application of the Birthday Paradox. In our latitudes, the chance is about 3.8%, i.e. once in four weeks in average, that two consecutive coordinates are within of 10 km of another. The chance for a 10 km range repetition within of one week is already about one fourth. --Ekorren 21:29, 23 April 2009 (UTC)
