Efficiency can be measured by the amount of work divided by the number of resources involved. They just redced the amount of resources (the WTMD Lane). If they also reduced staffing by the same amoun, then I'd supposed they are slightly more efficient here.
But the passengers do not benefit in this situation; only TSA.
Had TSA
added another XRay to an existing WTMD then they'd still have two x-rays per WTMD and having an extra X-Ray machine in the overall system would benefit passengers.
