In this final instructional segment, the video advises on how to compensate for both the stair nosing and the thickness of the riser when laying out and cutting the stair stringers. For instance, if risers are 3/4 inch thick and there's a 1-inch nosing, these dimensions must be factored into the stringer's starting point and subsequent cuts. The presenter stresses that to achieve the desired 10-inch tread run with a 1-inch nosing, everything (the stringer layout) needs to be shifted back by the combined dimension of the nosing and the riser thickness (e.g., 1 inch + 3/4 inch = 1 and 3/4 inches) to ensure correct overall stair alignment and prevent stair tread run from being too short.
