That's maximum efficiency.

Exactly. But, one does have to consider tank flow if it's enough to maintian detritus in suspension so the low sump flow can take it. Most have that taken care of no problem. Some, however use sump flow as a contributor to overal tank turnover. If you don't get the crud from the tank to the sump, it doesnt matter what flow the sump/skimmer has.
