Comment(by pramsey):

 Here's the issue:

 http://trac.osgeo.org/postgis/browser/trunk/postgis/gserialized_estimate.c#L1416

 The thing is, removing this will open other problems, since this was added
 precisely because edge cases were being lost. At the end of the day, the
 "estimated" box is 1% larger than the sampled box, which is *itself*
 smaller than the *actual* box, since... it's a *sample*! The key word here
 is "estimated". I incline towards leaving thing as they are.
