Basic required_hits question

[Jessica Brennan]

My required_hits is set to 4.0 yet an email that scored 4.0 was not marked 
as spam. I thought it was supposed to be "hits equal to or greater than 
the filter level", right? I have found documents online saying that SA 
marks spam at "hits equal to or greater than the filter level" and 
documents that say it marks spam "greater than the filter level". I was 
just wondering which it was.
