Sure, but don't try to hack this metric too much. Manufacturers use it and don't try to game it. They actually want to improve it. Apple partners with Foxcon to get this number at 5, and wouldn't have it at 5 if they didn't believe Foxcon could manage demand. Apple would maintain inventories in their warehouse if that was the case.
This metric speaks as much about Foxcon's success as it does Apple's.
