Are you missing out leaving important data standing on the outside?
Every now and then you can't beat a bit of Meat Loaf, the singer not the food, as I've not had the pleasure to taste it. I recently found myself recalling a cult classic "Standing on the outside" not because of any failed break up but thinking about the abundance of data available externally that can be used in combination with your internal data. Unfortunately, many are still leaving this data standing on the outside.
