Google Maps API - geocoding accuracy chart?

Question

Where in the Google Maps API docs can I find a table explaining the accuracy values of Geocode lookups?

Has the range of values changed in between V2 and V3

I don't know if you saw, but V3 does not include accuracy anymore. It seems that there is a different way though. If you add the results of the address_component elements you get a similar result. Disclaimer: I am not 100% sure about this but it looks like that they included the accuracy this way. I am currently doing some testing is this the way to go.

Here an example:

I searched for: 555 Pearl Street, Boulder

Here the result with Address Level accuracy (8 levels deep).

        [address_component] => Array
            (
                [0] => SimpleXMLElement Object
                    (
                        [long_name] => 555
                        [short_name] => 555
                        [type] => street_number
                    )

                [1] => SimpleXMLElement Object
                    (
                        [long_name] => Pearl St
                        [short_name] => Pearl St
                        [type] => route
                    )

                [2] => SimpleXMLElement Object
                    (
                        [long_name] => Boulder
                        [short_name] => Boulder
                        [type] => Array
                            (
                                [0] => locality
                                [1] => political
                            )

                    )
