Be careful on your digs. It was intentionally added to avoid having to size the FDC based on system demand in recognition that the FDC will typically slam the main supply check closed on typically occupancy hazard facilities but facilities like storage and high rise, it depends (sprinklers only since as pointed out standpipes FDC are calc's). Also if the main supply fails, the pumper truck can always juice their supply up further.
