I am probably doing something wrong but there seems to be a discrepancy between the data-explorer and the API. For instance,
This query has a total of 48048. http://api.superuser.com/1.0/users?sort=reputation&order=desc&pagesize=100&page=1
But the data-explorer has a total of 58630
http://data.stackexchange.com/superuser/query/new using select count(*) from users;
Am I missing something here? Is there a difference between registered and non-registered maybe?
