title: In ARKit how long and how accurately will a placed object remain in world space?
body: <p>New to ARKit and trying to get clarification on how it remembers where things are. </p>
  
  <p>A Terrible Use Case Example...but it conveys the thought...</p>
  
  <p>I create a virtual post it note just about an inch to the left of it on the desk. Next day I come back and my reminder says to look at the note. I open the app and...because I saved the world space info, when I replace the object is it still an inch to the left of the iMac?</p>
  
  <p>What if I have a post it at both my home and work desks?  I guess I’m confused with exactly how accurate is the positioning of items I put into ARKit space vs how GPS works in terms of remembering and determining position. </p>
  
  <p>Thanks!</p>
