  Understand the logic behind it, but you probably statistically have
  just as much chance of being correct as you do incorrect.

Just like the old days with AOL & their proxies.  There are not as many 3G or proxy / VPN users are there are standard 
users.  Therefore, it works - mostly.  (Or can work, I have no idea if the particular company / tool under discussion 
is actually useful.)

Data is data.  It can be misinterpreted, but it is still data.

    "The new method zooms in through three stages to locate a target
    computer. The first stage measures the time it takes to send a data
    packet to the target and converts it into a distance - a common
    geolocation technique that narrows the target's possible location to
    a radius of around 200 kilometres.
    (..)
    Finally, they repeat the landmark search at this more fine-grained
    level: comparing delay times once more, they establish which
    landmark server is closest to the target. The result can never be
    entirely accurate, but it's much better than trying to determine a
    location by converting the initial delay into a distance or the next
    best IP-based method. On average their method gets to within 690
    metres of the target and can be as close as 100 metres - good enough
    to identify the target computer's location to within a few streets."
    It seems to me to be a rather flaky way of finding out your
    estimated location. But I guess it could be helpful when the
    objective is just to create some global database of demographics for
    marketing and privacy invasion purposes, where specifics of an
    individual's exact location don't really matter.
    Besides the latter can always be subpoenaed. ;-)
    One more reason to use VPN and other such techniques to hide your
    location.
    Greetings,
    Jeroen
