On my tanks with no ATO a point or two lower then NSW gives me a buffer zone since their topped off by hands to a mark or blue tape on glass. Have seen no health or growth disturbances in corals or fish in the tanks that run a bit below.
Plus I don’t have salinity probes or tank controllers yet to get alerts or can easily glance at. I do have several wify inkbirds temp controllers that i get alerts though if needed.
