You don't want to add up test results like that; you should OR them 
together instead, to avoid the potential for test results adding up to 77 
and wrongly becoming UNSUPPORTED.  (In this case of course there aren't 
enough tests to get to 77, but the principle applies that you should avoid 
the test return being a count of something.)
