As per pool luck... Go there and view the charts... Yesterday was good, but the majority of the week was bad.
It probably wouldn't hurt to cite on
http://www.labratmining.com/currentHashrate.php specifically what pool or pools you are pointing the miners at, and if possible, a way of actually viewing the mining stats rather than everyone waiting for the sporadic updates (the pretty chart is nice and all... but I'd like to see actual numbers myself).
