   The precision is a red herring, in my opinion, since the fact that you   
   can't get out of the Apple WPS database even though you followed all of   
   Apple's legally binding published policies is the main privacy issue.   
      
   Apple's decision is legally, morally & ethically reprehensible, so I will   
   start working on getting Apple to change their decision any way that I can.   
      
   However, to the point of the raw precision in the Apple WPS database, I've   
   modified the open source Apple bssid locator tools to report raw integer   
   values in addition to conversion to the human-readable GPS coordinates.   
      
   Here are raw/converted values for the bssid lookup on the access point   
   located near 4302 Josey Cir, Shreveport, LA 71109 (as a random AP lookup).
