Then you could move the bench and test piece to sea level and measure the same 250 cfm of flow. When the bench reports 250 cfm of flow, it is a measure of how well the test piece flows air, but is not a measurement of real airflow in the bench. Until recently, bench flow was the only answer of interest to flowbench users.
