For example date_last_campaign isn't in the documentation at all (and probably should be string not int), and all of the numeric values are doubles not ints. Some logicially should be ints like GroupCount, but ClickRate,OpenRate,TargetSubRate,AvgUnsubRate,AvgSubRate all come in as doubles and turn to 0 when serialized by the api.
Converting date_last_campaign to a string actually got a result, while only open_rate and click_rate come in as trouble doubles, though that might just be because I have a limited sample.
ListInfo.ListStats doesn't seem to correspond with the response from mailChimp api [http://apidocs.mailchimp.com/api/2.0/lists/list.php].
