If the CPD was a medical-vocational decision, the rationale must include an explanation
            of the functional limitations (e.g., the ability to lift and carry, sit, stand, and
            walk) based on the medical findings and a statement of residual functional capacity
            (RFC). The adjudicator will compare this explanation with an assessment of the “MIRS
            RFC” (current functional capacity considering only the impairment(s) that was present
            at the CPD). For more information on the “MIRS RFC," see DI 28015.300.
