Common sense. 3 shifts running at $22 per tape and only takes 1 employee per shift. The gross profit margins are through the roof. They had a major expansion on the tape reading business over the summer.
Plenty has changed since 2008. Dig deeper. Hell, they had more tape reading revenue in two days in 2009 at the tale end of June than they had in all of 2008 so it's silly to use 2008 as any kind of a measure of anything.
