If your decision procedure is so simple that you always throw out any container with zero dots and always keep any container with non-zero dots, then perhaps it saves a small amount of time.

But that's a pretty coarse decision procedure, both because there might be an item that's very important but gets used less than once per year and because there might be a container that is 99% full of unused stuff but happens to have 1 item that gets used once a year.
