This is what I've come up with so far:

//Level 9 gets you lat, lon, address, country(Passed Stanley Park,
Blackpool)(Premise (building name, property name, shopping center,
etc.) level accuracy)
//Level 8 gets you lat, lon, address, city, county, state, postal,
country (Passed 1060 West Addison Street, Chicago, IL)(Address level
accuracy)
//Level 7 gets you lat, lon, address, city, state, postal, country
(Haight and Ashbury St, San Francisco)(Intersection level accuracy)
//Level 6 gets you lat, lon, county, state, country (Passed 99, rue de
Rivoli, Paris 75001)(Street level accuracy)
//Level 5 gets you lat, lon, city, state, postal, country (Passed
49519 US.  9 digit postal doesn't do any better)(Post code (zip code)
level accuracy)
//Level 4 gets you lat, lon, state, country (Passed the city and
country)(Town (city, village) level accuracy)
//Level 3 Have not been able to recreate
//Level 2 gets you lat, lon, state, country (michigan, us)(Region
(state, province, prefecture, etc.) )
//Level 1 gets you lat, lon, country (Passed US.  Lat and Lon plot in
the middle of Kansas but there were others in the middle of the
country too)(Country level accuracy)
//Level 0 gets you lat (Passed Europe)

Level 9 seems unreliable.  Yellowstone National Park got me a 602 even
after I added the state or country.  The comment on the continent
being level 0 is dead-on.  I cannot even say for sure if the same
elements will be populated each time for the same accuracy level.  The
only theory that I have from this data is that the accuracy level
corresponds to the GEOs only, and the only reason that Stanley Park,
Blackpool could be the most accurate, is it is a registered GEO, and
not estimated from a street address.  Just a theory, but the only one
that I could think of that could fit the term and make Stanley Park,
Blackpool more precise than a street address.  It would have to be a 9
square foot park to beat a street address.

It appears that the only safe thing to do is to ignore accuracy
levels, and check for undefined or null objects with every query and
see what I have to work with.

Thanks!
