I wish I could find a good source. Basically I heard it from people like these (http://www.elitetrader.com/vb/showthread.php?threadid=198241 http://www.elitetrader.com/vb/showthread.php?threadid=198241), but I don't know for sure they're not just echoing what they heard (like I just did). There was one guy I remember reading, who seemed pretty authoritative, who echoed it, but I can't find a link to him.
